Convert JSON to CSV — export structured data for spreadsheets
Paste a JSON array of objects or upload a .json file, then export a CSV that works in Excel, Google Sheets, and data import systems.
JSON to CSV Converter
How it works
This converter turns a JSON array of objects into a CSV file for spreadsheets and data imports. It automatically collects keys across objects and outputs a consistent column set.
- For best results, provide a JSON array:
[{"a":1},{"a":2}]. - Choose semicolon delimiter if your system expects European CSV formatting.
- Conversion happens locally in your browser.

Tips & Troubleshooting
These quick notes help you get clean, reliable results with Convert JSON to CSV — export structured data for spreadsheets—especially when you’re uploading to forms, emailing files, or preparing documents for submission.
Best results
- Use UTF‑8 encoding when converting CSV/JSON so special characters stay intact.
- Standardize headers before converting—consistent columns prevent broken outputs.
- Export a small sample first to confirm the formatting before converting a large file.
- After conversion, open the output once to confirm columns, dates, and decimals.
Troubleshooting
- If columns shift in CSV, values may contain commas—ensure they are quoted properly.
- If JSON is nested, flattening may be needed before conversion to CSV.
- If dates change formats, set the column format in Excel after import.
- If output looks garbled, re-save your source as UTF‑8 and retry.
