CSV to JSON Converter
Convert CSV, TSV, or other delimited text to JSON locally in your browser. Your pasted data is not uploaded.
How to use it
What this CSV to JSON Converter is for
Use this CSV to JSON Converter when you need to turn spreadsheet exports, copied table rows, fixture data, or simple delimited text into JSON for backend examples.
It is useful for API mock responses, import previews, documentation snippets, tests, seed data, and quick data cleanup before using a JSON-focused tool.
How to use it
Paste CSV, TSV, semicolon-delimited, or pipe-delimited text into the input box.
Choose whether the first row should be treated as headers. Keep this enabled when you want an array of objects with meaningful property names. Disable it when the file has no header row and generated keys such as column1 and column2 are enough.
Use Convert JSON for readable formatted JSON, or Minify JSON when you need compact output. Enable type inference only when you want values like true, false, null, and numbers converted from strings.

CSV to JSON Converter questions
Does this CSV to JSON Converter upload my data?
No. Parsing and JSON generation run locally in your browser, and the tool does not send pasted CSV data to a server.
Can this handle quoted CSV fields?
Yes. It handles common quoted CSV cells and escaped double quotes.
Should I enable type inference?
Use type inference only when you want values such as true, false, null, and numbers converted from strings. Leave it off when IDs or ZIP codes must stay strings.
Can I output arrays instead of objects?
Yes. Use the output shape control to generate either an array of objects or an array of arrays.
