Needing help on bulk replacing letters and characters in Word

[Xavier]

In a document I am working on, it was OCR'd from a very large document (9,000 pages) that was previously in files with holes punched into each page.

Often during the OCR the holes were coming up as a Capital letter C followed by a return (as per the attached). If I just delete capital C's from the entire document I screw up many words. Is there a way I can only delete a capital C when it is immediately followed by a space, then a return?

I'm also hoping to remove situations where I have a return at the end of a line, followed by another return on the next line as per the attached I just want the document to have one return as per the first paragraph) rather than a return then another return as per the proceeding three lines. Any help with this one too would be awesome.

Another issue I have met is where tables have randomly been inserted into the document. Is there a way I can bulk remove the weird formatting symbols to get rid of the tables (see attached)?

Finally I have an issue where I need to bulk add next page section breaks everytime my document has the characters "/86 " (without the quotation marks). If I try to Control +H to do a bulk replace, then it won't allow me to add a section break.

Thanks in advance to all.

You can select each of the tables and convert to text or alternatively, cut the entire text from the file and then Paste Special as Text Only to remove all the table structures.

A section break is ^b in the Replace dialog. Is that what you are using to replace the /86 instances?
