How to convert JSON to CSV
- Step 01

Run the conversion

Download your new CSV file immediately. Multiple outputs pack into a single ZIP archive.
Why convert JSON to CSV
Flatten JSON arrays into columns for Excel, Sheets, or BI tools. Ideal when an API dump needs to become a human-readable table.
When to use this tool
- You received API data as JSON and need a spreadsheet.
- Non-developers need to filter or chart the records.
- You are auditing export shape before a database load.
Good to know
- Nested objects may be flattened or stringified — deeply nested trees are imperfect in CSV.
- All rows should share a similar key set for clean columns.
- Encoding stays UTF-8 friendly for most modern tools.
- Browser limit: about 50 MB per file, up to 20 files per batch. PDFs are capped at 50 pages; large sheets at about 100,000 rows.
- Need a bigger file? For bigger PDFs or workbooks, use Adobe Acrobat, LibreOffice, Microsoft Office, or a desktop batch tool, then convert a trimmed copy here if you only need a quick private pass.
