WhatsApp Chat Exporter

Project Overview

WhatsApp lets us export our conversations in .txt format but reading that .txt file becomes a real pain as the data is presented in somewhat structured form with no text wrapping. Sure, there are tools that work in browser or have system-level access to your device, just to process the chat transcripts, but the security of such programs raises a huge red flag as whether they are storing our data on their servers or not.

So I thought why not build a WhatsApp Chat transcript parser by myself that works within your web-browser?! I am no developer but I have basic knowledge about HTML and CSS. The quality of code produced by reasoning AI models such as o3 and DeepSeekR1 has really taken the world by surprise. So I set out to take help from these reasoning models to develop a parser by myself. So here it is, a browser-based WhatsApp Chat Transcript parser that leverages the Save as PDF option in your browser to transform those unreadable transcripts into printable pages! This tool will be very handy in case if you want to preserve the chat history of a person who is no longer within us or you intend to run a corpus or discourse analysis on a WhatsApp Chat.

I have also added some "interesting" insights and functionality such as the total number of messages, filtering of messages by the sender or by date, a bar graph representing the number of messages sent in a month, support for message rendering through Markdown syntax etc etc.
