Up to version 2.3, opening large and complex spreadsheets could take quite long. Most of that time was spent verifying if rows, columns, or pages have been hidden. If they are, the converter will also ignore them.
In most cases, though, users don't hide data and don't need that much precision. So by default, this setting is disabled. Faster, but if you have a hidden data, it will still be converted. Set to true if you don't want hidden content to enter your termbase.
