Questions about Excel to JSON

Are my files uploaded?

No. The file is opened and changed inside your browser, on your phone or computer. Nothing is sent to our servers.

Are empty cells kept?

Yes. In "rows as objects" an empty cell becomes null, so every row has the same fields.

Is it safe?

Yes. Excel to JSON works inside your browser. Your files are not uploaded anywhere, so nobody else can see them, and there are no waiting queues.
