.. attention:: Looking for maintainer



   I don't really use this package anymore and with my current lifestyle I don't

   have much time to maintain this project. The library as-is only supports

   gspread version <6. Updating this to support v6 might involve a fair bit of work

   which I unfortunately cant do. I'm happy to work with anyone who might want to

   maintain, or I can still accept PRs.



Overview

========



A package to easily open an instance of a Google spreadsheet and

interact with worksheets through Pandas DataFrames. It enables you to

easily pull data from Google spreadsheets into DataFrames as well as

push data into spreadsheets from DataFrames. It leverages

`gspread `__ in the backend for

most of the heavylifting, but it has a lot of added functionality

to handle things specific to working with DataFrames as well as

some extra nice to have features.



The target audience are Data Analysts and Data Scientists, but it can also

be used by Data Engineers or anyone trying to automate workflows with Google

Sheets and Pandas.



Some key goals/features:



-  Be easy to use interactively, with good docstrings and auto-completion

-  Nicely handle headers and indexes (including multi-level headers and merged cells)

-  Run on Jupyter, headless server, and/or scripts

-  Allow storing different user credentials or using Service Accounts

-  Automatically handle token refreshes

-  Enable handling of frozen rows and columns

-  Enable filling in all merged cells when pulling data

-  Nicely handle large data sets and auto-retries

-  Enable creation of filters

-  Handle retries when exceeding 100 second user quota

-  When pushing DataFrames with MultiIndex columns, allow merging or flattening headers

-  Ability to handle Spreadsheet permissions

-  Ability to specify ``ValueInputOption`` and ``ValueRenderOption`` for specific columns



Installation / Usage

====================



To install use pip:



.. code-block:: console



    $ pip install gspread-pandas



Or clone the repo:



.. code-block:: console



    $ git clone https://github.com/aiguofer/gspread-pandas.git

    $ python setup.py install



Before using, you will need to download Google client credentials for

your app.



Client Credentials

------------------



To allow a script to use Google Drive API we need to authenticate our

self towards Google. To do so, we need to create a project, describing

the tool and generate credentials. Please use your web browser and go to

`Google console `__ and :



-  Choose **Create Project** in popup menu on the top.

-  A dialog box appears, so give your project a name and click on

   **Create** button.

-  On the left-side menu click on **API Manager**.

-  A table of available APIs is shown. Switch **Drive API** and click on

   **Enable API** button. Do the same for **Sheets API**. Other APIs might

   be switched off, for our purpose.

-  On the left-side menu click on **Credentials**.

-  In section **OAuth consent screen** select your email address and

   give your product a name. Then click on **Save** button.

-  In section **Credentials** click on **Add credentials** and switch

   **OAuth client ID** (if you want to use your own account or enable

   the use of multiple accounts) or **Service account key** (if you prefer

   to have a service account interacting with spreadsheets).

-  If you select **OAuth client ID**:



   -  Select **Application type** item as **Desktop app** and give it a name.

   -  Click on **Create** button.

   -  Click on **Download JSON** icon on the right side of created

      **OAuth client IDs** and store the downloaded file on your file system.

-  If you select **Service account key**



   -  Click on **Service account** dropdown and select **New service account**

   -  Give it a **Service account name** and ignore the **Role** dropdown

      (unless you know you need this for something else, it's not necessary for

      working with spreadsheets)

   -  Note the **Service account ID** as you might need to give that user

      permission to interact with your spreadsheets

   -  Leave **Key type** as **JSON**

   -  Click **Create** and store the downloaded file on your file system.

-  Please be aware, the file contains your private credentials, so take

   care of the file in the same way you care of your private SSH key;

   Move the downloaded JSON to ``~/.config/gspread_pandas/google_secret.json``

   (or you can configure the directory and file name by directly calling

   ``gspread_pandas.conf.get_config``



Thanks to similar project

`df2gspread `__ for this great

description of how to get the client credentials.



You can read more about it in the `configuration docs

`__

including how to change the default behavior.



Example

=======



.. code:: python



    import pandas as pd

    from gspread_pandas import Spread, Client



    file_name = "http://stats.idre.ucla.edu/stat/data/binary.csv"

    df = pd.read_csv(file_name)



    # 'Example Spreadsheet' needs to already exist and your user must have access to it

    spread = Spread('Example Spreadsheet')

    # This will ask to authenticate if you haven't done so before



    # Display available worksheets

    spread.sheets



    # Save DataFrame to worksheet 'New Test Sheet', create it first if it doesn't exist

    spread.df_to_sheet(df, index=False, sheet='New Test Sheet', start='A2', replace=True)

    spread.update_cells('A1', 'B1', ['Created by:', spread.email])

    print(spread)

    # @gmail.com', Spread: 'Example Spreadsheet', Sheet: 'New Test Sheet'>



    # You can now first instanciate a Client separately and query folders and

    # instanciate other Spread objects by passing in the Client

    client = Client()

    # Assumming you have a dir called 'example dir' with sheets in it

    available_sheets = client.find_spreadsheet_files_in_folders('example dir')

    spreads = []

    for sheet in available_sheets.get('example dir', []):

        spreads.append(Spread(sheet['id'], client=client))



Troubleshooting

===============



EOFError in Rodeo

-----------------



If you're trying to use ``gspread_pandas`` from within

`Rodeo `_ you might get an

``EOFError: EOF when reading a line`` error when trying to pass in the verification

code. The workaround for this is to first verify your account in a regular shell.

Since you're just doing this to get your Oauth token, the spreadsheet doesn't need

to be valid. Just run this in shell:



.. code:: python



   python -c "from gspread_pandas import Spread; Spread('','')"



Then follow the instructions to create and store the OAuth creds.



This action would increase the number of cells in the workbook above the limit of 10000000 cells.

-------------------------------------------------------------------------------------------------



IMO, Google sheets is not the right tool for large datasets. However, there's probably good reaons

you might have to use it in such cases. When uploading a large DataFrame, you might run into this

error.



By default, ``Spread.df_to_sheet`` will add rows and/or columns needed to accomodate the DataFrame.

Since a new sheet contains a fairly large number of columns, if you're uploading a DF with lots of

rows you might exceed the max number of cells in a worksheet even if your data does not. In order

to fix this you have 2 options:



1. The easiest is to pass ``replace=True``, which will first resize the worksheet and clear out all values.

2. Another option is to first resize to 1x1 using ``Spread.sheet.resize(1, 1)`` and then do ``df_to_sheet``



There's a strange caveat with resizing, so going to 1x1 first is recommended (``replace=True`` already does this). To read more see `this issue `_
