csvtodashboard is a complete, local-first toolkit for working with CSV files. Every tool below runs in your browser — no account, no required upload for the browser tools.
Most free CSV converters output everything as quoted strings. Ours infers types from your data — numbers stay numbers, booleans stay booleans, dates stay dates.
Find what's wrong, drop what's redundant, slice down to the rows that matter, split into manageable chunks.
SELECT, WHERE with AND/OR, ORDER BY, LIMIT — no database, no upload, no setup.
Validate → dedupe → filter → sort → SQL → split → export, all from one pipeline that re-runs as you change steps.
Once your data is shaped, the dashboard generates KPIs, charts, anomaly flags, and a sortable table — automatically.
Yes. No signup, no trial, no paid tier. The site is ad-supported.
No. The browser tools parse and process your file locally — you can verify in DevTools → Network that no requests fire when you drop a file.
Currently around 15 — converters, cleaners, a SQL query tool, a workflow builder, and the dashboard builder. See the lists above by category.
CSV (comma, semicolon or tab), TSV, and Excel files (.xlsx and .xls). Multi-sheet workbooks show a picker.
