Frequently asked questions

How do I join two CSV files on a common column?

Open the Join Tables tab, paste both CSVs and pick the key column. It performs SQL-style inner, left, right and full outer joins without needing a database.

How do I make a pivot table or group by sum from a CSV?

Use the Pivot Table tab to group rows and summarize with sum, avg, count, min or max. No spreadsheet software is needed.

How do I change a CSV delimiter, for example semicolon to comma?

The Redelimit tab converts between comma, semicolon, tab and pipe separators.

Can I edit a CSV in the browser and chart it?

Yes. The Spreadsheet Editor tab is an inline grid, the Chart tab draws bar, line or pie charts from the data, and Statistics shows per-column stats such as counts, unique values, min, max and mean.

Which formats can CSV be converted to?

JSON, YAML, SQL, XML, HTML tables, query strings and Markdown tables, in both directions.

Is my data uploaded to a server?

No. This tool runs entirely in your browser — your input is processed locally on your device and is never uploaded or stored on a server.
