Macro needed to change all article numbers in a 600+ pages catalog according to a cross-ref excel sheet

Hello there!

I have a cross-ref excel sheet with old article numbers | new article numbers.

Basically about 23.000 rows with two columns, ARTICLEOLD | ARTICLENEW

Now I have a large catalog as a Corel Document that has 616 pages. Not all but most of the article numbers are within this document as text objects which need to be converted into the new article numbers. Unfortunately I lack VBA skills. If you could help me out with ideas how to make a macro that updates the article numbers page by page according to the excel sheet, that'd be great.

Thanks in advance everyone.
