FAQ

What JSON format is supported?

An array of objects ([{...},{...}]) is supported. Each object's keys become column headers.

Is my data sent to a server?

No. All processing is done in your browser.

Can large JSON files be converted?

It depends on browser memory, but a few thousand rows should work fine.

What happens with nested objects?

Nested objects are stored as JSON strings in a single cell. A flat structure is recommended.

What is the name of the downloaded file?

The file is downloaded as 'output.xlsx' by default.
