CSV to JSON Converter
What is CSV to JSON Converter
The CSV to JSON converter transforms tabular data in CSV format into a JSON array of objects. Each column header becomes a key and each row becomes an object in the resulting array. It handles quoted fields, commas inside values, and escaped quotes, making it reliable for real-world CSV files exported from spreadsheets, databases, or analytics tools.
How to use
- Paste your CSV data into the text area (the first row must be the header).
- Click Convert to JSON.
- Review the JSON array output.
- Click Copy to copy the JSON to your clipboard.
When to use it
Need to turn a spreadsheet export into JSON? Paste your CSV and get a clean array in one click, ready to drop into an API call or save as a test fixture. No parser to write and no manual reformatting, even when the file runs to thousands of rows.
Frequently asked questions
Does it handle quoted fields with commas inside?
Yes. Fields enclosed in double quotes that contain commas or line breaks are parsed correctly, including escaped double quotes ("").
What happens if rows have different numbers of columns?
Missing values are filled with an empty string. Extra columns beyond the header are ignored.
Does it work with semicolon-separated files?
This tool uses comma as the delimiter. For semicolon-separated files, use Find & Replace in your text editor to swap semicolons for commas first.
Is my data sent to a server?
No. The conversion runs entirely in your browser. Your CSV data never leaves your device.
Can I share this tool with my inputs pre-filled?
Yes. The URL updates automatically as you type. Copy it from the address bar or use the Share button — anyone who opens the link will see your exact inputs ready to go.
