Excel to JSON, in your browser
When you need spreadsheet data inside an app, API or script, JSON is the format you want — and copying cells by hand is painful. Mynify converts an Excel workbook straight to a JSON array of objects, right in your browser, with nothing uploaded. That privacy matters because spreadsheets so often hold sensitive figures.
How it works
Mynify reads the first worksheet, uses the header row as keys, and turns each data row into a JSON object — giving you a tidy array like [{ "name": "Ada", "total": 42 }, …] that’s ready to drop into code, seed a database, or feed an API.
When to use it
- Seeding a database or test fixtures from a spreadsheet.
- Feeding app or API data that lives in Excel.
- Inspecting spreadsheet data as structured JSON.
