Quick Start

Click here to go to the introduction with more details about CleverCSV. If you're in a hurry, below is a quick overview of how to get started with the CleverCSV Python package and the command line interface.

For the Python package:

# Import the package
>>> import clevercsv

# Load the file as a list of rows
# This uses the imdb.csv file in the examples directory
>>> rows = clevercsv.read_table('./imdb.csv')

# Load the file as a Pandas Dataframe
# Note that df = pd.read_csv('./imdb.csv') would fail here
>>> df = clevercsv.read_dataframe('./imdb.csv')

# Use CleverCSV as drop-in replacement for the Python CSV module
# This follows the Sniffer example: https://docs.python.org/3/library/csv.html#csv.Sniffer
# Note that csv.Sniffer would fail here
>>> with open('./imdb.csv', newline='') as csvfile:
...     dialect = clevercsv.Sniffer().sniff(csvfile.read())
...     csvfile.seek(0)
...     reader = clevercsv.reader(csvfile, dialect)
...     rows = list(reader)

And for the command line interface:

>> df">

# Install the full version of CleverCSV (this includes the command line interface)
$ pip install clevercsv[full]

# Detect the dialect
$ clevercsv detect ./imdb.csv
Detected: SimpleDialect(',', '', '\\')

# Generate code to import the file
$ clevercsv code ./imdb.csv

import clevercsv

with open("./imdb.csv", "r", newline="", encoding="utf-8") as fp:
    reader = clevercsv.reader(fp, delimiter=",", quotechar="", escapechar="\\")
    rows = list(reader)

# Explore the CSV file as a Pandas dataframe
$ clevercsv explore -p imdb.csv
Dropping you into an interactive shell.
CleverCSV has loaded the data into the variable: df
>>> df

Introduction

CSV files are awesome! They are lightweight, easy to share, human-readable, version-controllable, and supported by many systems and tools!
CSV files are terrible! They can have many different formats, multiple tables, headers or no headers, escape characters, and there's no support for recording metadata!

CleverCSV is a Python package that aims to solve some of the pain points of CSV files, while maintaining many of the good things. The package automatically detects (with high accuracy) the format (dialect) of CSV files, thus making it easier to simply point to a CSV file and load it, without the need for human inspection. In the future, we hope to solve some of the other issues of CSV files too.

CleverCSV is based on science. We investigated thousands of real-world CSV files to find a robust way to automatically detect the dialect of a file. This may seem like an easy problem, but to a computer a CSV file is simply a long string, and every dialect will give you some table. In CleverCSV we use a technique based on the patterns of row lengths of the parsed file and the data type of the resulting cells. With our method we achieve 97% accuracy for dialect detection, with a 21% improvement on non-standard (messy) CSV files compared to the Python standard library.

We think this kind of work can be very valuable for working data scientists and programmers and we hope that you find CleverCSV useful (if there's a problem, please open an issue!) Since the academic world counts citations, please cite CleverCSV if you use the package. Here's a BibTeX entry you can use:

@article{van2019wrangling,
        title = {Wrangling Messy {CSV} Files by Detecting Row and Type Patterns},

Installation

CleverCSV is available on PyPI. You can install either the full version, which includes the command line interface and all optional dependencies, using

$ pip install clevercsv[full]

or you can install a lighter, core version of CleverCSV with

$ pip install clevercsv

Usage

CleverCSV consists of a Python library and a command line tool called clevercsv.

Python Library

We designed CleverCSV to provide a drop-in replacement for the built-in CSV module, with some useful functionality added to it. Therefore, if you simply want to replace the builtin CSV module with CleverCSV, you can import CleverCSV as follows, and use it as you would use the builtin csv module.

import clevercsv

CleverCSV provides an improved version of the dialect sniffer in the CSV module, but it also adds some useful wrapper functions. These functions automatically detect the dialect and aim to make working with CSV files easier. We currently have the following helper functions:

detect_dialect: takes a path to a CSV file and returns the detected dialect
read_table: automatically detects the dialect and encoding of the file, and returns the data as a list of rows. A version that returns a generator is also available: stream_table
read_dataframe: detects the dialect and encoding of the file and then uses Pandas to read the CSV into a DataFrame. Note that this function requires Pandas to be installed.
read_dicts: detect the dialect and return the rows of the file as dictionaries, assuming the first row contains the headers. A streaming version called stream_dicts is also available.
write_table: write a table (a list of lists) to a file using the RFC-4180 dialect.

Of course, you can also use the traditional way of loading a CSV file, as in the Python CSV module:

import clevercsv

with open("data.csv", "r", newline="") as fp:
  # you can use verbose=True to see what CleverCSV does
  dialect = clevercsv.Sniffer().sniff(fp.read(), verbose=False)
  fp.seek(0)
  reader = clevercsv.reader(fp, dialect)
  rows = list(reader)

For large files, you can speed up detection by supplying a smaller sample to the sniffer, for example:

dialect = clevercsv.Sniffer().sniff(fp.read(10000))

You can also speed up encoding detection by installing cCharDet, it will automatically be used when it is available on the system.

That's the basics! If you want more details, you can look at the code of the package, the test suite, or the API documentation. If you run into any issues or have comments or suggestions, please open an issue on GitHub.

Command-Line Tool

To use the command line tool, make sure that you install the full version of CleverCSV (see above).

The clevercsv command line application has a number of handy features to make working with CSV files easier. For instance, it can be used to view a CSV file on the command line while automatically detecting the dialect. It can also generate Python code for importing data from a file with the correct dialect. The full help text is as follows:

USAGE
  clevercsv [-h] [-v] [-V]  [
   
    ] ... [
    
     ]

ARGUMENTS
  
            The command to execute
  
     
                 The arguments of the command

GLOBAL OPTIONS
  -h (--help)     Display this help message.
  -v (--verbose)  Enable verbose mode.
  -V (--version)  Display the application version.

AVAILABLE COMMANDS
  code            Generate Python code for importing the CSV file
  detect          Detect the dialect of a CSV file
  explore         Drop into a Python shell with the CSV file loaded
  help            Display the manual of a command
  standardize     Convert a CSV file to one that conforms to RFC-4180
  view            View the CSV file on the command line using TabView

Each of the commands has further options (for instance, the code and explore commands have support for importing the CSV file as a Pandas DataFrame). Use clevercsv help for more information. Below are some examples for each command.

Note that each command accepts the -n or --num-chars flag to set the number of characters used to detect the dialect. This can be especially helpful to speed up dialect detection on large files.

Code

Code generation is useful when you don't want to detect the dialect of the same file over and over again. You simply run the following command and copy the generated code to a Python script!

$ clevercsv code imdb.csv

# Code generated with CleverCSV

import clevercsv

with open("imdb.csv", "r", newline="", encoding="utf-8") as fp:
    reader = clevercsv.reader(fp, delimiter=",", quotechar="", escapechar="\\")
    rows = list(reader)

We also have a version that reads a Pandas dataframe:

$ clevercsv code --pandas imdb.csv

# Code generated with CleverCSV

import clevercsv

df = clevercsv.read_dataframe("imdb.csv", delimiter=",", quotechar="", escapechar="\\")

Detect

Detection is useful when you only want to know the dialect.

$ clevercsv detect imdb.csv
Detected: SimpleDialect(',', '', '\\')

The --plain flag gives the components of the dialect on separate lines, which makes combining it with grep easier.

$ clevercsv detect --plain imdb.csv
delimiter = ,
quotechar =
escapechar = \

Explore

The explore command is great for a command-line based workflow, or when you quickly want to start working with a CSV file in Python. This command detects the dialect of a CSV file and starts an interactive Python shell with the file already loaded! You can either have the file loaded as a list of lists:

$ clevercsv explore milk.csv
Dropping you into an interactive shell.

CleverCSV has loaded the data into the variable: rows
>>>
>>> len(rows)
381

or you can load the file as a Pandas dataframe:

$ clevercsv explore -p imdb.csv
Dropping you into an interactive shell.

CleverCSV has loaded the data into the variable: df
>>>
>>> df.head()
                   fn        tid  ... War Western
0  titles01/tt0012349  tt0012349  ...   0       0
1  titles01/tt0015864  tt0015864  ...   0       0
2  titles01/tt0017136  tt0017136  ...   0       0
3  titles01/tt0017925  tt0017925  ...   0       0
4  titles01/tt0021749  tt0021749  ...   0       0

[5 rows x 44 columns]

Standardize

Use the standardize command when you want to rewrite a file using the RFC-4180 standard:

$ clevercsv standardize --output imdb_standard.csv imdb.csv

In this particular example the use of the escape character is replaced by using quotes.

View

This command allows you to view the file in the terminal. The dialect is of course detected using CleverCSV! Both this command and the standardize command support the --transpose flag, if you want to transpose the file before viewing or saving:

$ clevercsv view --transpose imdb.csv

Version Control Integration

If you'd like to make sure that you never commit a messy (non-standard) CSV file to your repository, you can install a pre-commit hook. First, install pre-commit using the installation instructions. Next, add the following configuration to the .pre-commit-config.yaml file in your repository:

repos:
  - repo: https://github.com/alan-turing-institute/CleverCSV-pre-commit
    rev: v0.6.6   # or any later version
    hooks:
      - id: clevercsv-standardize

Finally, run pre-commit install to set up the git hook. Pre-commit will now use CleverCSV to standardize your CSV files following RFC-4180 whenever you commit a CSV file to your repository.

Comments

Make CleverCSV a pre-commit hook
Would you consider making CleverCSV a pre-commit hook, by adding a .pre-commit-hooks.yaml file to your repository? This would allow people to have csv files in their repositories to automatically check them whenever they want to commit them.

The only thing missing to make it work is, as I understand:

An option to overwrite the input file instead of printing to STDOUT (I think this could be a flag, like --in-place)

The possibility of clevercsv to accept a list of file arguments to process.

(Probably implemented already) A different exit status whether the input file was altered (!=0) or not (=0).

I can file a PR for the .pre-commit-hooks.yaml, if you agree (after the above points are implemented).

Thanks for your consideration!

help for data type detection

CleverCSV looks very promising ! I try to use this package to extract csv to database. We need detect datatype of each column. Is there anyway this package can help ? The other question, is it possible(performance/memory) we can handle multi GB data by using this package ?

Thanks for help. hong

Date delimiter prevales on column delimiter

Hi everyone,

I have a lot of files with long formated dates (with timestamps). The file is delimited by a "," but the timestamps splits hours, minutes, seconds... with a ":". Example : item1,item2,2022-03-28 17:24:10,item4,2022-01-02 22:43:59,item6

I should have : Column 1 | Column 2 | Column 3 | Column 4 | Column 5 | Column 6 item1 | item 2 | 22-03...:10| item4 | 22-01...:59| item6 but it gives the following result : C 1 |C2| C3 |C4| C5 item1,item 2,2022-03-28 17|24|10,item4,2022-01-02 22|43|59,item6

Same thing with some very surprising characters recognised as delimiters when the delimiter is really obvious and more frequent :

4819736,lilly354128,fr,Alin,lilly354128,,,,Lilly,DARS,,2 rue des ezda,,4581350,SAINT LA FORET,,FR,+330000000,,,,,,,,,,,,644365,"""LE TEMPS DE DÉCOUVRIR...""","* COFFRET DÉCOUVERTE SEPT PARFUMS On this line, CleverCSV have found a delimiter.... and the delimiter is the star "*" ! I really don't understand the logic ?

I have resolved this issue with a pre-analysis algorithm that verifies, when there are 2 potentials delimiters, if one of them verifies a common formats like, dates, time, adress, floating numbers (coma case). But the annoying thing is that I need to parse two times, one with my pre-analysis and then with CleverCSV. That could be very nice to have a Clever version for this too.

Have a nice day !

Suggestion: Make Pandas dependency optional

Hello, First of all thanks for writing this cool library. Is it possible to make Pandas an optional dependency? From looking at the code briefly, it seems it should work without Pandas too if you are just dealing with reading csv files. There are projects that don't need Pandas but could use this library. Thanks

the delimiter guess by clevercsv is ":", it should be ",".

detection is really slow in some cases

Hey there, first of all, great project!

The following commands takes a significant amount of time:

> python3 -m timeit -n 1 -- "from clevercsv import Detector; Detector().detect('fileurl="file://$PROJECT_DIR$/../aaaaaa_aaaaaaa_aaaaa/.aaa/." filepath=$')" 
1 loop, best of 5: 13.2 sec per loop
python3 -m timeit "from clevercsv import Detector; Detector().detect('a'*18)" 
1 loop, best of 5: 8.24 sec per loop

After benchmarking a little bit, the apparent cause is that the unix_path and url regexes in the detector are susceptible to a ReDOS .

These change, which replace the regexes with (hopefully) equivalent ones fixes the most oblivious issues:

-    "url": "((https?|ftp):\/\/(?!\-))?(((([\p{L}\p{N}]*\-?[\p{L}\p{N}]+)+\.)+([a-z]{2,}|local)(\.[a-z]{2,3})?)|localhost|(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}(\:\d{1,5})?))(\/[\p{L}\p{N}_\/()~?=&%\-\#\.:]*)?(\.[a-z]+)?",
-    "unix_path": "(\/|~\/|\.\/)(?:[a-zA-Z0-9\.\-\_]+\/?)+",
+    "url": "((https?|ftp):\/\/(?!\-))?(((?:[\p{L}\p{N}-]+\.)+([a-z]{2,}|local)(\.[a-z]{2,3})?)|localhost|(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}(\:\d{1,5})?))(\/[\p{L}\p{N}_\/()~?=&%\-\#\.:]*)?(\.[a-z]+)?",

1 loop, best of 5: 4.17 msec per loop
:0: UserWarning: The test results are likely unreliable. The worst time (347 msec) was more than four times slower than the best time (4.17 msec).

Is there a way to distinguish between ,, and ,"", in the reader?

PostgreSQL RDBMS has CSV export/import functionality (https://www.postgresql.org/docs/9.6/sql-copy.html) that has a quirk in its CSV format: they treat ,, as SQL NULL and ,"", as a zero length string value. These are different values, and it is important to be able to distinguish between them.

Is there a way to parse a line like foo,,bar,"",baz as ['foo', None, bar, '', 'baz'] ? Without forking and playing with the state machine in C, of course. :-)

Add instructions on using pre-commit

I believe this PR fixes #24.

@lcnittl I made an attempt at adding the pre-commit hook myself (hope you don't mind). It turned out that registering the hook with the repo link will always require pre-commit to install CleverCSV from the repo, which requires compilation (as you discovered as well). ~~By using repo: local and specifying CleverCSV as a dependency, we ensure that the pre-compiled wheel will be installed from PyPI.~~

Update for posterity: the solution we went with is to use a dummy package that depends on clevercsv[full], which contains the pre-commit hook. This PR has been updated with the new instructions.

Unicode characters cause UnicodeEncodeError from clevercsv.wrappers.write_table on Windows 10

Hello and thank you for your work on this excellent library! I'm running on a Windows 10 machine and encountering a UnicodeEncodeError when attempting to write data that includes Unicode using clevercsv.wrappers.write_table.

It appears that adding an optional encoding argument to clevercsv.wrappers.write_table would fix this, as it works when I use the clevercsv.writer without the wrapper as a workaround (below).

Workaround:

with open("outfile.csv", "w", newline="", encoding="utf-8") as fp:
    w = clevercsv.writer(fp)
    w.writerows(data_list)

Please migrate away from setup.py
Hello!

setup.py has been deprecated for a while now (although support hasn't yet bet removed). It would be nice if this project moved away from it before something actually breaks :)

If you want to stick with setuptools, newer versions do support building via a PEP-617-style pyproject.toml file:

https://setuptools.pypa.io/en/latest/userguide/pyproject_config.html

https://peps.python.org/pep-0621

You can see an example of a migration to pyproject.toml with setuptools that I did here: https://github.com/jaseg/python-mpv/pull/241

Support Python 3.11

The csv module now disallows empty strings in Dialect escapechar or quotechar properties bpo-20028.

Maintain the current CleverCSV Dialect interface, but generate Dialects that Python 3.11 is happy with.

Fixes: #74
