From Excel (XLSX) data to JSON

Excel (XLSX) and JSON are two ways of writing the same structured data, so Morphr maps your records from one into the other with every field intact. It all happens on your device, which matters when the data is sensitive.

Excel (XLSX) and JSON, explained

XLSX is the modern Microsoft Excel workbook format, storing typed cells, formulas and multiple sheets. JSON is the dominant data-interchange format on the web, holding structured data as nested objects and arrays. Every programming language parses it natively.

Good to know

• • Your Excel (XLSX) files never leave your device — everything converts locally in the browser, so even confidential ones stay private.
• • Convert as many Excel (XLSX) files as you like at once; a batch comes back as a single ZIP.
• • Same data, different wrapper: the field names and values come through unchanged.
• • No sign-up, no watermark and no size limit beyond your device’s memory.

The private way to turn Excel (XLSX) into JSON

With Morphr, the whole conversion runs inside your browser tab using Morphr's own engine, so your file is never uploaded to a server, queued, or stored. That makes it a safe choice for personal photos, scanned documents and anything you'd rather not hand to a third party.
