CSV to JSON Converter

Convert table data to JSON

CSV is convenient for spreadsheets and exports, while JSON is often easier to use in APIs, tests, and web apps. This converter parses CSV locally and turns rows into either objects with headers or arrays without headers.

The parser supports quoted fields, escaped quotes, line breaks inside quoted fields, and common delimiters including comma, semicolon, and tab.

Useful workflows

• Turn a small spreadsheet export into JSON test data.
• Convert API examples from CSV tables into structured payloads.
• Inspect whether headers and rows line up before copying JSON.

FAQ

Is the CSV uploaded?

No. Parsing and conversion run in the browser.

Does it support quoted fields?

Yes. The parser handles quoted fields, escaped quotes, and line breaks inside quoted values.

What happens without headers?

You can turn headers off and the tool will output each row as an array.
