That request is on the vague side. You are advised in the Posting Guide to include code that begins an analysis and then requests assistance with specific difficulties. (You are also asked to do this in a plain text message since HTML tends to scramble messages.) The base package offers the `grep`, `sub`, and `gsub` functions which bring the power of regular expression to the R user. There are much more flexible that anything that Excel offers. Please look at:

?grep
?regex
