I wouldn't really call this a program I made, but the first two functions decide whether to open a file or not, and for each error is explained, for the third function, you put in a file and choose what you want to change and what to, I uploaded a version of this yesterday but it didn't have the .IGNORECASE to ignore if it's Capitalized or not, so yeah, i can do a lot with this.
