ExcelCategory — Pivoting & Filters

🧪 In progress

ExcelCategory is a cross-platform app designed to simplify the analysis and manipulation of Excel files, with a focus on usability, speed, and portability. The goal is to provide an intuitive tool for non-expert users who want to apply filters, view data in a readable way, and save it in common formats (Excel and PDF). After uploading an Excel file, you can apply filters via a guided interface, view the results as cards, and continue refining the selection through dropdown menus. The app supports export and printing, making it useful in administrative, educational, and business contexts.
