Large scale find and replace needed

[chairwars]

I have a word document with several mail merged letters in it (500+ all with the same letter content) one page after another and I need to replace the letter content in all of them but leave the address details as they are. I can't use the find and replace as it only does small amounts of text. The address details were originally mail merged into the document but I no longer have the data source so I can't just make a new letter and it would take forever to change it manually.

Does anyone know of a large scale find and replace option or another way I can handle this?

TIA.

If you're likely to use this again, it's worth extracting the addresses into another new data source.

Otherwise, you could export it to a text file and use a text file editor to find and replace the text in the letter.

Then, try re-importing back into word. I have never tried that, but it might work.

To test it, create a sample with only a few letters to see how the formatting re-imports.

Thanks engine. Any suggestions on a text file editor? I tried notepad but that has the same limit as word.
