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.
