I downloaded my data from Facebook in a .json format. I used Python with Jupyter Notebook to play with data. The json and pandas libraries are very useful to read and display data in a stylized way. I added some columns to the data such as date (since the available time was a millisecond timestamp) and total characters for each row (each row represents a sent message). Finally, I exported the data as an .xls file and opened it with Tableau to make the graphs.
