How CSV to JSON Works
The first line of your CSV is used as field names. Each following line becomes one JSON object, matching each comma-separated value to its column header. Quoted fields (which may contain commas or escaped double quotes as "") are parsed correctly, not just split on every comma.
How to Use This Tool
- Paste your CSV data, including a header row.
- Select Convert to JSON.
- Check the table preview, then copy or download the JSON.
Example
The CSV name,age
Alice,30
Bob,25 converts to [{"name":"Alice","age":30},{"name":"Bob","age":25}].
Helpful Tips
- Uncheck Convert numeric-looking values to numbers if you need values like phone numbers or ZIP codes to stay as text instead of being turned into numbers.
- If a field itself contains a comma, wrap it in double quotes in your CSV so it isn't split incorrectly.
Frequently Asked Questions
Does this handle quoted fields with commas inside them?
Yes, fields wrapped in double quotes can contain commas, and doubled quotes ("") inside a quoted field are treated as a single literal quote character.
What if my CSV uses semicolons instead of commas?
This tool expects comma-separated values. If your file uses a different delimiter, replace it with commas first (careful of any commas that should stay inside quoted fields).
Is my data uploaded anywhere?
No, parsing and conversion both happen entirely in your browser.
This tool runs entirely in your browser. Your input is not uploaded to any server.
