What is ExploreMyData?
A free, privacy-first data explorer that runs entirely in your browser.
ExploreMyData is a free CSV viewer online that lets you open, analyze, and transform data files directly in your browser. Unlike other tools, your data never leaves your device. Everything runs locally using DuckDB WASM, a full SQL engine compiled to WebAssembly.
With 30+ data operations, you can filter rows, sort columns, remove duplicates, create pivot tables, join multiple files, clean messy data, extract date parts, add computed columns, and export results. Every operation generates SQL and becomes a step in a reproducible pipeline.
Upload CSV, Parquet, JSON, Excel, PDF, XML, Word, TXT, or DuckDB files. Export to any of those formats plus HTML and TSV. Build multi-step pipelines, create charts, and use AI to describe transformations in plain English.
Completely free, no sign-up, works in any modern browser. Open a Parquet viewer, an online Excel analyzer, or a browser-based SQL tool without uploading a single byte.
