CSV to JSON

Convert CSV into JSON

Use this converter to transform comma-separated values (CSV) into JSON. This is useful when you need to import spreadsheet exports into JavaScript code, APIs, or tooling that expects JSON.

Common use cases

• Turning Excel/Google Sheets exports into JSON fixtures
• Converting data for REST API payloads
• Generating configuration objects from tabular data

Tips

• Make sure the first row contains headers if you want meaningful JSON keys.
• If your CSV uses a different delimiter (e.g. ;), normalize it before converting.
• One value per column: commas inside quotes are treated as separators too (no RFC 4180 quoting), so avoid commas within a single field.
• Rows with fewer values than headers keep the missing columns as empty strings.
