How to convert .xlk files to .accda format.
Converting Microsoft Excel Backup Files directly to Access Add-in Files (.xlk to .accda conversion) seems highly unlikely, at least to our knowledge, since both file types are of different nature and serve different purposes.
We are not aware of any software or (online) conversion solution, which would allow users to directly convert .xlk to .accda.
The database currently does not contain any xlk software converter.
