Frequently Asked Questions

What JSON format is expected?

An array of flat objects, e.g. [{"name":"John","age":30}]. Each object becomes one row, each key becomes a column.

Is my file uploaded to a server?

No. Both conversions happen entirely in your browser using JavaScript — your data never leaves your device.

Which Excel formats are supported?

Both .xlsx and the older .xls format can be uploaded for conversion to JSON.
