Before you compare
Does xlLens upload my workbooks?

What is the difference between the trial and xlLens?
The trial includes every feature for 3 days. Purchasing removes the time limit.
Is the license a subscription?
No. The purchased version does not expire. Updates and email support are included for 12 months; later major versions, new features, and support may be sold separately.
