TSV to JSON Converter
Convert tab-separated data (copied from Excel) into a clean JSON array of objects.
Paste tab-separated data — the format you get when copying cells from Excel or Google Sheets — and get a clean JSON array of objects keyed by the header row. It is the quickest way to turn a spreadsheet selection into API-ready data without saving a file. Everything runs in your browser.
Have comma-separated data instead? Use CSV to JSON. Need XML or YAML? See JSON to XML and JSON to YAML.
