Discovery of the day

I had an excellent day today.

Meaning, I used Excel for almost everything I had to do at work.

I discovered that it's pretty easy to update an old spreadsheet to include the 8th digit in the phone numbers (Costa Rica added a digit last year) by inserting a column and then pasting in a formula that adds 20,000,000 to the old number.

Formulas and mass pasting are a good thing, given that it's a 645-row spreadsheet, and each row includes two to four phone numbers.
