Purpose: Convert a single spreadsheet file into any number of JSON files.

Features supported:

Supports conversion from spreadsheets in .xlsx format.

Conversion can be performed even while the file is open in another program. Note: If you edit the spreadsheet without saving, the conversion will still be based on the previously saved (older) version of the file.

Can simultaneously generate multiple JSON files at specified output paths.

Supports not only regular fields but also arrays of objects.
