JSONL to Excel Converter
/jsonl-to-excelConvert JSONL (NDJSON) data into an Excel spreadsheet with one JSON object per row and keys as columns.

FAQ
Frequently asked questions
Everything you need to know about jsonl to excel converter.
Which column order is used?
Columns follow the order in which keys first appear across your objects, so the spreadsheet reads naturally from the first object onward.
What happens to nested values?
Nested objects and arrays become compact JSON text inside the cell, so nothing is truncated and you can expand the data later if needed.
Which sheet is created?
The workbook contains one sheet named Data with the JSON keys as the header row and one row per JSONL line.
Can I open the file on any platform?
Yes, the output is a standard .xlsx file that opens in Excel, Google Sheets, LibreOffice, and Apple Numbers.
Why do I get an error on a specific line?
Each line must be a valid JSON object; the error reports the offending line number so you can remove or repair it before converting.
