Hi

I have a workbook with lots of analytic data from my company which I want to share with other people not associated with the company. Obviously I can't share private data so I'm wondering if theres a quick way to modify all the data I have with 'fake numbers' which means I could share it. With fake numbers no privacy rules will be breached etc.

Is there a quick way to randomly change all numbers by +/- 10-20%?

Thanks
