CSV to JSON Converter

Convert table data to JSON

CSV is convenient for spreadsheets and exports. JSON is easier to use in APIs, tests, and web apps. Parse CSV locally into 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.

Best for

• Small spreadsheet exports and pasted tables.
• CSV examples that need to become API-ready JSON.
• Quick inspection before copying data into docs, tests, or fixtures.

CSV to JSON examples

• Rows without headers can be converted into nested JSON arrays.
• Quoted CSV fields with commas stay together when the parser reads them.
