Drop in your JSON files and get CSV files back. Everything runs in your browser: nothing is uploaded, there is no file size limit and you do not need an account.
Accepts: images (PNG, JPG, WebP, GIF, BMP, SVG, ICO, AVIF, HEIC), PDF, Word (.docx), Markdown, HTML, TXT,
spreadsheets (XLSX, XLS, ODS, CSV, TSV), JSON, XML, YAML, and video (MP4, MOV, WebM, MKV) or audio. Video can become GIF (first 15 seconds), WebM or MP4 (recorded in real time, so it takes as long as the video), a still image, or just the audio. Mixed batches are fine.

Why convert JSON to CSV?
Open JSON data in Excel or Google Sheets by turning it into CSV.
JSON is a structured data format used by websites and APIs. CSV is plain-text table data that opens in any spreadsheet app.
Your files never leave your device
Most online converters upload your files to a server. This one does the work inside your browser, so your JSON files stay on your computer or phone. That also means no waiting for uploads and no cap on file size.
Good to know
Works best with an array of objects. Nested objects are stored in a single cell as JSON text.
Frequently asked questions
Are my JSON files uploaded to a server?
No. The conversion runs inside your browser on your own device. Your files are not sent to us or anyone else. Besides loading this page and, for some formats, a small helper library, nothing is downloaded or uploaded while you convert, and you can confirm that in your browser's developer tools (Network tab).
Is there a limit on file size or number of files?
We do not set one. The only limit is your device's memory, so for very large batches (thousands of files, or very big videos) work in several groups.
Do I need to sign up, install anything or accept a watermark?
No. There is no account, no install and no watermark. Open the page, add your files and download the results.
How do I convert many JSON files at once?
Drag them all in together or pick them in the file chooser. They are converted one after another, and Download All saves the results as one ZIP (a single result downloads directly).
Are there any limitations converting JSON to CSV?
Works best with an array of objects. Nested objects are stored in a single cell as JSON text.
