Private table tools
Make messy data
clear and trustworthy.
Open a table, understand what it contains, make cleanup changes, and download a new result. CSV, TSV, and table-shaped JSON stay on your device by default.
Most files open on this device. If online processing is needed, you will see exactly what will be uploaded and can cancel first.

Straight answers
Before you open a file
What stays on this device?
Common CSV, TSV, and JSON tasks. The app never uploads a file without asking you first.
When is online processing needed?
Some spreadsheet, Parquet, and SQLite files, or work that is too large for your device. You see the limits and deletion policy before anything is uploaded.
Are formulas run?
No. Imported spreadsheet formulas, macros, external links, scripts, and embedded objects are never executed.
