1) Office Tabs

Office Tabs lets you manage multiple documents with ease, introducing a document bar below your Word, Excel, and PowerPoint ribbons.

Delete a Certain Number of Leading Characters

Suppose you have a column that lists part numbers for a certain product. Let’s say all parts begin with the letter “R”, and you decide to remove this letter from all values under this column. Your first instinct may be to run Find and Replace, but what if the column contains the letter “R” in other parts of its data, such as “R33TRF”? In that case, Find and Replace would remove all the “R”s, not just the leading ones.
