Convert Spreadsheet Rows to JSON

Turn CSV headers and rows into JSON objects for API imports, mock data, scripts, and configuration files, or convert JSON arrays back into CSV for spreadsheet use.

Headers, Quotes and Empty Cells Matter

Check column names, quoted commas, line breaks inside cells, empty values, and number formatting before sending the converted data to an import or API endpoint.

Where CSV and JSON Conversion Fits

Use this converter for quick data handoffs between spreadsheets, admin panels, no-code tools, test payloads, and developer workflows that expect structured JSON.

How It Works

CSV to JSON Converter parses CSV data and converts it into a JSON array with header row values as object keys. It handles quoted fields, commas in values, and custom delimiters, producing clean JSON for use in APIs and applications.

When to Use It

Use this when you have spreadsheet data that needs to be loaded into a web app, when an API expects JSON but your source is a CSV export, or when transforming a data export for processing in JavaScript.

How to Use

Paste your CSV data including the header row.
Set the delimiter if it is not a standard comma.
Click Convert to produce the JSON output.
Copy the JSON array for use in your application.

Questions People Ask

What happens to fields that contain commas?

Fields enclosed in double quotes that contain commas are handled correctly. The parser treats the quoted content as a single value.

Can I convert JSON back to CSV?

Yes. Switch to JSON-to-CSV mode, paste your JSON array, and the tool produces a CSV with headers from the object keys.

What if my CSV uses semicolons instead of commas?

Set the delimiter field to semicolon and the parser will split on that character instead.
