Python 3 scripts to convert chat logs from various messaging platforms into Pandas DataFrames. Can also generate histograms and word clouds from the chat logs.


10 Jan 2020: UPDATED ALL THE THINGS! Thanks to mar-muel and manueth, pretty much everything has been updated and improved, and WhatsApp is now supported!

21 Oct 2018: Updated Facebook Messenger and Google Hangouts parsers to make them work with the new exported file formats.

9 Feb 2018: Telegram support added thanks to bmwant.

24 Oct 2016: Initial release supporting Facebook Messenger and Google Hangouts.

Exported data

Data exported for each message regardless of the platform:

Column Content
timestamp UNIX timestamp (in seconds)
conversationId A conversation ID, unique by platform
conversationWithName Name of the other people in a direct conversation, or name of the group conversation
senderName Name of the sender
outgoing Boolean value whether the message is outgoing/coming from owner
text Text of the message
language Language of the conversation as inferred by langdetect
platform Platform (see support matrix above)

Exporting your chat logs

1. Download your chat logs

Google Hangouts

Warning: Google Hangouts archives can take a long time to be ready for download - up to one hour in our experience.

  1. Go to Google Takeout:
  2. Request an archive containing your Hangouts chat logs
  3. Download the archive, then extract the file called Hangouts.json
  4. Move it to ./raw_data/hangouts/

Facebook Messenger

Warning: Facebook archives can take a very long time to be ready for download - up to 12 hours! They can weight several gigabytes. Start with an archive containing just a few months of data if you want to quickly get started, this shouldn't take more than a few minutes to complete.

  1. Go to the page "Your Facebook Information":
  2. Click on "Download Your Information"
  3. Select the date range you want. The format must be JSON. Media won't be used, so you can set the quality to "Low" to speed things up.
  4. Click on "Deselect All", then scroll down to select "Messages" only
  5. Click on "Create File" at the top of the list. It will take Facebook a while to generate your archive.
  6. Once the archive is ready, download and extract it, then move the content of the messages folder into ./raw_data/messenger/


Unfortunately, WhatsApp only lets you export your conversations from your phone and one by one.

  1. On your phone, open the chat conversation you want to export
  2. On Android, tap on > More > Export chat. On iOS, tap on the interlocutor's name > Export chat
  3. Choose "Without Media"
  4. Send chat to yourself eg via Email
  5. Unpack the archive and add the individual .txt files to the folder ./raw_data/whatsapp/


The Telegram API works differently: you will first need to setup Chatistics, then query your chat logs programmatically. This process is documented below. Exporting Telegram chat logs is very fast.

2. Setup Chatistics

First, install the required Python packages using conda:

conda env create -f environment.yml
conda activate chatistics

You can now parse the messages by using the command python <platform> <arguments>.

By default the parsers will try to infer your own name (i.e. your username) from the data. If this fails you can provide your own name to the parser by providing the --own-name argument. The name should match your name exactly as used on that chat platform.

# Google Hangouts
python hangouts

# Facebook Messenger
python messenger

# WhatsApp
python whatsapp


  1. Create your Telegram application to access chat logs (instructions). You will need api_id and api_hash which we will now set as environment variables.
  2. Run cp and fill in the values for the environment variables TELEGRAM_API_ID, TELEGRAMP_API_HASH and TELEGRAM_PHONE (your phone number including country code).
  3. Run source
  4. Execute the parser script using python telegram

The pickle files will now be ready for analysis in the data folder!

For more options use the -h argument on the parsers (e.g. python telegram --help).

3. All done! Play with your data

Chatistics can print the chat logs as raw text. It can also create histograms, showing how many messages each interlocutor sent, or generate word clouds based on word density and a base image.


You can view the data in stdout (default) or export it to csv, json, or as a Dataframe pickle.


You can use the same filter options as described above in combination with an output format option:

  -f {stdout,json,csv,pkl}, --format {stdout,json,csv,pkl}
                        Output format (default: stdout)


Plot all messages with:

python breakdown

Among other options you can filter messages as needed (also see python breakdown --help):

  --platforms {telegram,whatsapp,messenger,hangouts}
                        Use data only from certain platforms (default: ['telegram', 'whatsapp', 'messenger', 'hangouts'])
                        Limit by conversations with this person/group (default: [])
                        Limit to messages sent by this person/group (default: [])
                        Remove messages by these senders/groups (default: [])
                        Remove all messages by this sender (default: [])
                        Filter by messages which contain certain keywords (default: [])
                        Limit by outgoing messages (default: False)
                        Limit by incoming messages (default: False)

Eg to see all the messages sent between you and Jane Doe:

python breakdown --filter-conversation "Jane Doe"

To see the messages sent to you by the top 10 people with whom you talk the most:

python breakdown -n 10 --incoming-only

You can also plot the conversation densities using the --as-density flag.

Word Cloud

You will need a mask file to render the word cloud. The white bits of the image will be left empty, the rest will be filled with words using the color of the image. See the WordCloud library documentation for more information.

python cloud -m raw_outlines/users.jpg

You can filter which messages to use using the same flags as with histograms.


Install dev environment using

conda env create -f environment_dev.yml

Run tests from project root using

python -m pytest

Improvement ideas

  • Parsers for more chat platforms: Discord? Signal? Pidgin? ...
  • Handle group chats on more platforms.
  • See open issues for more ideas.
