Data Workbench · query CSV with SQL in browser
Query CSV with SQL in your browser
A zero-upload SQL workflow for local CSV, TSV, and JSONL files with cleanup and export steps.
Workflow
- Import the file and confirm schema.
- Write a SELECT query with filters, groupings, ordering, and limits.
- Inspect query results, chart a small result set, or create a pivot summary.
- Export CSV, JSONL, or XLSX from the local result set.
Important notes
- Monaco and DuckDB-Wasm are the production hardening direction.
- Queries should be cancellable and recover cleanly from errors.
