CSV ↔ JSON Converter
Convert CSV to JSON and JSON arrays back to CSV. The converter uses the first row as column headers and creates one JSON object per row. Handles quoted fields, commas inside values, and multiple separator styles.
FAQ
How do I convert a CSV file to JSON?
Paste or upload your CSV. The first row becomes the JSON keys. Each subsequent row becomes an object in the output array.
What if my CSV has semicolons instead of commas?
Select the semicolon separator option before converting. European CSV exports often use semicolons because commas appear in number formatting (1.234,56).
What is the difference between CSV and JSON?
CSV (Comma-Separated Values) is a flat table format — rows and columns, like a spreadsheet. JSON (JavaScript Object Notation) supports nested structures, arrays within objects, and mixed types.
