what I should have said was can you export a table from your version of access to a text file or csv and then bring that back in? I've had some quirks with formatting before now, can't remember what exactly other than it was to do with seperators or tabs or something.
for a while I though it was a compatability issue with diff' versions but I've just created a new database, built a table, exported as .xls and tried to import it back.
