Questions people ask

Is my document uploaded?

No. It is opened and converted in your browser on this device.

Why does Excel show my CSV in one column?

Excel guesses the separator from your system settings. Converting to .xlsx here avoids that: every column lands in its own column.

Do PIN codes keep their leading zero?

Yes. Values that start with 0 stay as text, so 007 does not become 7.
