CSV to JSON Converter
Convert CSV (comma-separated values) data into JSON format instantly — with automatic header detection, multiple delimiter support, and clean output.
What Does This Tool Do?
CSV is a common format for tabular data — spreadsheets, database exports, reports. JSON is the standard format for data in web applications and APIs. This tool bridges the two: paste your CSV data and get clean JSON output ready to use in any application.
Key Features
How to Use This Tool
- Paste your CSV data into the Input box.
- Check "First row = headers" if your CSV has a header row.
- Select the delimiter (comma, tab, semicolon, or pipe).
- Click Convert to get JSON output.
How It Works
The CSV is split into rows by newlines. Each row is split into fields by the selected delimiter, handling quoted fields correctly. If headers are enabled, the first row becomes the keys for each JSON object. All subsequent rows become JSON objects with those keys.
Common Use Cases
Frequently Asked Questions
What if my CSV has commas inside fields?
Fields containing commas should be wrapped in double quotes in the CSV format. The converter handles quoted fields correctly.
Can I convert back from JSON to CSV?
Use a separate JSON to CSV converter for the reverse operation.
