Frequently asked questions
Is my data uploaded?
No. The editor runs entirely in your browser. Your files never leave your device, and nothing is sent to a server.
Which formats can I open?
CSV, TSV, JSON, JSONL (NDJSON), XLSX, XLS, SQLite databases and SQL dump files. You can export back to CSV, TSV, JSON, JSONL, XLSX, SQLite or SQL.
Can I edit the data?
Yes. Sort and filter columns, edit individual cells, add or remove rows and columns, then export the result in the format you need.
