CSV to JSON Converter

What does this tool do?

The CSV to JSON Converter transforms comma-separated value (CSV) data into a JSON array of objects. The first row is treated as headers, which become the keys in the resulting JSON objects.

How to use this tool

1. Paste your CSV data into the input field (first row must be headers)
2. Click Convert
3. Toggle Pretty print to control JSON indentation
4. Copy the JSON output

Common use cases

• Importing spreadsheet data into a JavaScript application
• Converting exported CSV reports to JSON for API consumption
• Transforming database exports for use in web applications
• Processing data from Google Sheets or Excel exports
• Batch converting tabular data for NoSQL databases

Example

Input CSV:

name,age,city
Alice,30,New York
Bob,25,San Francisco

Output JSON:

[
  {"name": "Alice", "age": "30", "city": "New York"},
  {"name": "Bob", "age": "25", "city": "San Francisco"}
]

Notes

• Quoted fields (e.g., "San Francisco") and fields containing commas are handled correctly
• All values are output as strings — type conversion is not applied
