Convert CSV (comma- or custom-separated values) into a JSON array. When the first row is marked as a header, each subsequent row becomes an object keyed by column names.
Options
- Separator: comma, semicolon, tab, or space
- Header row: treat row one as property names
Limitations
Quoted fields with embedded separators are supported for common cases. Invalid row widths return an error. Very large files are held in browser memory only.
When to use it
Move spreadsheet exports into JSON-first APIs, seed unit tests with tabular fixtures, or inspect CSV structure before loading into analytics notebooks. Processing never leaves your browser.
