CSV to JSON Converter — Parse CSV Online

What is CSV to JSON Conversion?

CSV (Comma-Separated Values) stores tabular data as plain text rows. JSON (JavaScript Object Notation) is a nested key-value format used by APIs and web apps. Converting between them maps column headers to JSON keys and row values to JSON values.

Why Convert CSV to JSON?

REST APIs consume JSON. If you export data from Excel, Google Sheets, or a database, it comes out as CSV. Converting to JSON lets you directly use that data in a Node.js script, a POST request body, or a JavaScript application without writing a parser.

Key Benefits

• Instant CSV → JSON conversion in browser
• Handles header rows, quoted fields, commas inside values
• Output is formatted and readable
• No data leaves your browser
• Supports large files

How to Use CSV to JSON Converter

1. Paste your CSV data or upload a .csv file
2. Check that the first row is headers (toggle if needed)
3. View the JSON output instantly
4. Copy or download the result

Example Use Case

You exported a list of users from a MySQL database as CSV. You need to seed a new MongoDB collection with that data. Paste the CSV, get a JSON array of objects, paste into your Node.js seed script — done in under a minute.

Tips

• Ensure your CSV has a header row for meaningful JSON keys
• Quoted fields with commas are handled correctly
• Empty cells become null or empty string in JSON
• Use the YAML/JSON converter after if you need YAML output
