Calc Guide

Removing personal data
You may wish to ensure that personal data, versions, notes, hidden
information, or recorded changes are removed from files before you
send them to other people or create PDFs from them.
In Tools > Options > OpenOffice.org > Security > Options, you
can set Calc to remind (warn) you when files contain certain
information and remove personal information automatically on saving.
To remove personal and some other data from a file, go to File >
Properties. On the General tab, uncheck Apply user data and then
click the Reset button. This removes any names in the created and
modified fields, deletes the modification and printing dates, and resets
the editing time to zero, the creation date to the current date and time,
and the version number to 1.
To remove version information, either go to File > Versions, select the
versions from the list and click Delete, or use Save As and save the
file with a different name.
