Apologies for the self-promotion, but I've done something similar for Telegram, and I believe some people here might be also' interested in that.

I also wanted to record more of my life, so I created a Telegram bot that saves all messages you send it into a Google Spreadsheet.

Hashtags can be used to split the text into sheets and columns, if so desired. Besides jotting down quick thoughts, this is very handy for short-form journaling such as tracking expenses, workouts, mood, period, weight, diet, etc., with the added bonus of easy charting and summarization from within the spreadsheet. It also supports pictures and other attachments that are uploaded automatically to Google Drive and linked into the spreadsheet.

Feel free to check it out, it's free of charge and does not require any registration: https://t.me/gsheet_notes_bot
