Questions

My JSON is an object, not a list. Does it work?
If the object holds one array inside it, that array is used. A single flat object becomes a one-row CSV.
What happens to nested objects?
Their fields become columns named parent.child. Lists inside a value are written as JSON text in the cell.
Why semicolon?
Excel in countries that use a comma for decimals expects semicolons between columns.
Is the file uploaded?
No.
