Hello Newsgroup

My macro creates *.xls reports as it grinds through its iterative
calculations.

Unfortunately, now that it has finished, each of the 120 output files has an
incorrect text entry in cell D2. Instead of saying "Hello" in D2 I want to
replace it with "Goodbye."

How can I replace "Hello" with "Goodbye" in each of the 120 files without
opening them individually. Is there an easy way to search and replace for
all files within a directory?

Thank you

W
