What it does

This tool turns a JSON array of objects into CSV that opens cleanly in Excel, Google Sheets or Numbers. The column set is the union of every key across the objects, in first-seen order.

A single object becomes one row, and any nested value is written as JSON text inside its cell.

Quoting and delimiters

Fields that contain the delimiter, a quote or a line break are wrapped in double quotes and escaped following RFC 4180, so the file re-imports without losing data.

Choose comma, semicolon, tab or pipe as the delimiter to suit your spreadsheet's locale.

Private and unlimited

Every conversion happens locally in your browser, so your data is never uploaded, logged or stored on a server. You can use it on confidential exports without a second thought, and it keeps working offline once the page has loaded.

There is no sign-up, no watermark and no row limit: the only ceiling is your device's memory.

Často kladené otázky

What JSON shape does it expect?

An array of objects where each item has the same keys, for example a list of records each with name and age. A single object is treated as one row. Nested objects and arrays are written as JSON text inside the cell, since CSV cannot represent variable-length structures.

Which delimiter should I use?

Comma is the standard. Pick semicolon in regions where the comma is the decimal separator (common in German and other European exports), tab for TSV files, or pipe when your values already contain commas.

Is there a row or file-size limit?

There is no fixed row cap or daily quota. Because everything runs locally the practical limit is your device's memory, which comfortably handles the tens of thousands of rows most exports contain.

Is my data uploaded anywhere?

No. The conversion runs entirely in your browser with client-side JavaScript, so nothing you paste or drop ever leaves your device. That makes it safe for spreadsheets that contain customer emails, financial figures or other sensitive data.
