What this CSV tool does
This page parses CSV in your browser, shows a table preview, and converts between CSV and JSON. Quoted cells, escaped quotes, and line endings are handled.
Conversion rules
For CSV to JSON, the first row is treated as the header and each subsequent row becomes an object keyed by the header. For JSON to CSV, the input must be an array of objects; the union of keys becomes the header.
