About

Data Workbench is a free, browser-based data cleaning and inspection tool. It parses your file the moment you drop it in, profiles every column, scores your data's overall health, and tells you exactly what's wrong — duplicate rows, missing values, mixed column types, untrimmed whitespace, and inconsistent structure. Then it offers one-click fixes for every issue it finds.There's nothing to install, no account to create, and no data ever leaves your machine. The entire tool runs client-side in your browser using JavaScript. It works with JSON, CSV, TSV, XML, YAML, and plain text files.
