Toolkit

Free CSV tools — for converting, cleaning, querying and visualizing.

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.

Convert

Format conversion with smart type detection.

Most free CSV converters output everything as quoted strings. Ours infers types from your data — numbers stay numbers, booleans stay booleans, dates stay dates.

Clean

Tidy a messy CSV.

Find what's wrong, drop what's redundant, slice down to the rows that matter, split into manageable chunks.

Query

Real SQL against your CSV.

SELECT, WHERE with AND/OR, ORDER BY, LIMIT — no database, no upload, no setup.

Workflow

Chain operations in one tab.

Validate → dedupe → filter → sort → SQL → split → export, all from one pipeline that re-runs as you change steps.

Visualize

Build a dashboard from your CSV.

Once your data is shaped, the dashboard generates KPIs, charts, anomaly flags, and a sortable table — automatically.
