Is there a way to undo Format Painter?

[SevsBo]

As per the title, I've accidentally applied Format Painter from one visual to a whole page, which has destroyed a whole day's work. Is there any way to undo this, as the Back button doesn't seem to be working?

@SevsBo  Hey, 
You can do the undo using ctrl +Z.
if you have save it then use previous day version or do the formating again

also you can refer this.

Use the Format Painter - Microsoft Support
