JSON to CSV Converter Pro
Convert JSON or NDJSON arrays into CSV with file drop, column reorder, flatten, and Excel BOM.
How to use
- Drop a .json file or paste a JSON array of objects (or NDJSON, one object per line).
- Choose delimiter, flatten nested objects, or enable Excel UTF-8 BOM as needed.
- Reorder columns if needed, then copy or download the CSV result.
Examples
Simple object array
Input: [{"name":"Ada","role":"Engineer"},{"name":"Grace","role":"Scientist"}]
Output: name,role Ada,Engineer Grace,Scientist
Each object becomes one CSV row with matching column headers.
Three-column export
Input: [{"sku":"A1","qty":10,"price":9.99},{"sku":"B2","qty":5,"price":14.5}]
Output: sku,qty,price A1,10,9.99 B2,5,14.5
Numeric values stay as plain CSV cells for Excel import.

Preparing JSON for Excel
Excel imports CSV most reliably when columns are flat and UTF-8 encoded. Nested JSON keys become column headers—preview the output before importing large files.
If you need to round-trip data, keep a copy of the original JSON and use the CSV to JSON converter after editing in Excel.
Common use cases
- Export API responses for Excel
- Convert sample datasets for testing
- Prepare JSON logs for spreadsheet review
