About CSV to JSON
Use the CSV to JSON converter to turn spreadsheet-style rows into an array of records. The first row supplies the property names. You can convert semicolon CSV to JSON or choose comma, tab, or automatic delimiter detection for other exports.
How to convert CSV rows into JSON objects
- Paste CSV with a unique header for each column.
- Choose the appropriate delimiter or Auto-detect, then select Process.
- Review the JSON array and download converted.json.
A practical example
- Input
name,count Ada,2
- Result
[ { "name": "Ada", "count": "2" } ]
Cell values remain strings. The count cell is not automatically inferred as a number.
Supported input and limitations
- Headers must be unique and rows must parse consistently. A headerless table is not automatically assigned invented field names.
- Input is limited to 5 MB. Type inference, schema mapping, and spreadsheet-file imports such as XLSX are not included.
Processing happens on your device. Read about local processing and optional workspace recovery.
Frequently asked questions
Are CSV numbers converted to JSON numbers?
No automatic type inference is enabled. Values such as 2 and 0012 remain strings, helping preserve leading zeros.
Can the converter handle commas inside quoted fields?
Yes, correctly quoted CSV fields are parsed as cells. Choose the correct delimiter and make sure embedded quotes are properly escaped.
