CSV to JSON Converter

Paste CSV data and convert it into formatted JSON arrays for APIs, fixtures, examples, and quick data cleanup.

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.

When this CSV converter helps

Use this converter when a spreadsheet export, pasted table, or tab-delimited list needs to become structured JSON that is easier to copy into code.

It is best for small and medium pasted datasets where you want to inspect the output before copying it into docs, API examples, tests, or fixtures.

CSV to JSON examples

  • name,email headers can become object keys in the JSON output.
  • Rows without headers can be converted into nested JSON arrays.
  • Quoted CSV fields with commas stay together when the parser reads them.

After converting CSV, use the JSON Formatter to validate or minify the output. For timestamp columns, check values with the Timestamp Converter. If rows need pattern cleanup, test expressions with the Regex Tester.

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.

Can I convert tab-separated values?

Yes. Choose the tab delimiter option when your copied table uses tabs instead of commas.

Is this a replacement for a database import tool?

No. It is intended for quick conversion, examples, and small pasted datasets.
