Developed a browser extension, the 'CircuitVerse Truth Table Filler', using JavaScript, HTML, and CSS to streamline filling truth tables in CircuitVerse's Combinational Analysis tool. The extension allows users to input data by pasting directly or uploading .csv and .xlsx files, leveraging the PapaParse and SheetJS (xlsx.js) libraries for file processing. It interacts with CircuitVerse pages via content scripts and background logic using browser extension APIs. This project is currently unpublished with plans to expand its utility (potentially under the name 'FilliT') to support a wider range of websites and input types, from simple forms to complex tables.
