03 · FAQ

Things people ask.

What can csvtodashboard do?
Convert CSV to JSON, SQL, Excel, Markdown, HTML and XML. Validate, dedupe, sort, filter, split and SQL-query a CSV. Chain those operations in a pipeline. Build an interactive dashboard from any CSV. All in one browser tab.
Yes. No signup, no trial, no card, no paid tier. Ad-supported — that's where the site's money comes from.
The browser tools process your CSV locally — your file is parsed and run in your tab, not on a server. You can verify in DevTools → Network: no requests fire when you drop a file. The exception is anything that explicitly fetches from a remote source (e.g. importing a Google Sheets URL), which the UI tells you about.
No. There is no signup, no login, no email field. There is no concept of a user account on the site.
CSV (comma, semicolon or tab delimited), TSV, and Excel files (.xlsx and .xls). Multi-sheet Excel workbooks show a picker so you can choose which sheet to load.
Up to roughly 50 MB and a few hundred thousand rows in modern browsers. Performance past that depends on your machine.
Yes — the CSV Workflow Builder at /csv-pipeline lets you validate, dedupe, filter, sort, query, and split in any sequence. Each step runs against the previous step's output.
Use Export HTML in the dashboard to bundle the data + the tool into a single self-contained file that opens offline. Or use Share Link to copy a URL with the filter/group-by/brush state encoded.
