Clean messy CSV & Excel files — visually, without scripts. 100% local, your data never leaves your machine.
DataFixer is a desktop app for anyone who deals with messy spreadsheets: e-commerce exports, SaaS analytics dumps, logs, address books, government datasets. Instead of writing formulas or scripts, you pick operations from a menu, preview every change with before/after highlights, and export clean data.
