Changed spreadsheet from english text to what looks like code

[suc8nc]

Hello,
Many years ago on excel 2010 I tampered with a spreadsheet I made after I saw a trick online that made the text unreadable (sort of looks like code) but it was not encrypting it or using any type of formula. Just trying to use the spreadsheet now (7 years later) and I cannot for the life of me remember how to do it, and I have had no luck searching the web. I know it was easy to do but that is all I remember. Any help would be appreciated.
Thanks
Gary

Yep, I know. I shoud have changed it back before saving it. It was simple to. I tihnk there was a keyboard shortcut and it just changed all the text to boxes, percentage signs etc.

Was it as simple as just changing the font to Symbol?

No it converted all my text from english to some other language. Cannot post the file either as the information is sensitive if it gets reverted back

It was something similar. But it was not just changing from Arial to another font in that regards.
