A small program written in Python 3 that lets you see statistics of any Facebook Messenger conversation. This project started of as a Valentines day surprise for my girlfriend inspired by this Reddit post.

The program fetches data such as:

• Start time
• End time
• Number of days
• Number of messages
• Number of words
• Average length of messages
• Average messages per day
• Most used emojis

It also generates a PDF containing the following plots (see pictures below)

• Who texts the most
• Timeline
• Activity by day
• Activity by weekday
• Most used emojis and who sent them

Firstly you will need to download or clone the repository, the latter can be done by typing

git clone https://github.com/davidkrantz/FacebookChatStatistics.git

in your terminal.

Download your Facebook data by following these instructions and chosing the format to be JSON. Note that you only have to download your messages in order for this program to work.

1. First you will have to install the needed packages. These are listed in the requirements.txt file and should be easily installed using pip with

pip3 install -r /path/to/requirements.txt

2. Run the script as below with the path to your JSON conversation as an argument, for example

python3 facebook_chat_statistics.py /Path/To/Conversation.json

NOTE: The number of top emojis is default set to 10, but can easily be changed to some other integer by changing the line nbr_of_top_emojis = 10 in facebook_chat_statistics.py.
