One file, queried and read and copied, is free forever. Joining several files, saving workspaces, query history and result exports are the paid version — $49 once, or $13 a week.
Your files
📄
Drop a file here
CSV, TSV, JSON, NDJSON or Parquet, anywhere on this page. It is read straight off your disk — nothing is sent anywhere, and nothing is stored.
We remember your queries, not your data. Reopening a workspace asks you to pick the file again — we never keep the file itself.
Workspace
Saved queries
None yet. Save the query in the editor to keep it with this workspace.
Saving this workspace so it comes back tomorrow is part of the paid version.
Workspace file
Export writes everything QueryDesk has kept on this device: every saved workspace, your query history and your column corrections. Share writes only the workspace open here, which is the one to hand a colleague — they open it against their own copy of the file. Neither carries a row of data.
History
Keeping a history of what you ran is part of the paid version.
Engine
Powered by DuckDB (MIT) running as WebAssembly in this tab. QueryDesk is not a DuckDB project and is not endorsed by DuckDB Labs. It is served from this site, never a CDN — which is what lets the page be sent a policy that forbids it from reaching anywhere else.
SQL
Results
Nothing yet. Open a file, then press ⌘↵.
