💡 Why Convert JSON to CSV?

✔️ Open JSON data in spreadsheets (Excel, Google Sheets, LibreOffice).
✔️ Easily analyse tabular data from APIs or databases.
✔️ Flatten nested objects automatically into JSON strings.
✔️ 100% client‑side – your data never leaves your browser.

💡 Pro Tip: For complex nested JSON, the tool converts inner objects/arrays into JSON strings. You can later parse them in your spreadsheet if needed. Use semicolon delimiter if your data contains commas.
