Knead and pound numbers

Chad Rothschiller, a program manager on the Excel team, discusses using formulas to 'clean up' data in Excel.


Excel is a great tool to use when you need to take data in one format, manipulate it into another format, and push the results along to another process, e.g. a database. In this context, Excel is a great landing pad or middle man, serving as a data transformation tool to move data from one system to another.

This example considers a sample data set and walks through the steps to clean up the data and perform various transformations on the data set to massage it into a more desirable format.


I'm sure you've been faced with at least one of theses problems:

  • Import the data and don't accidentally drop the leading zeros!

  • Formatting SSN

  • Inserting hyphens

  • Fixing up names

  • Lower case E-Mail Address

  • Format Home Phone

  • Inserting parenthesis & hyphens

  • Trim extra spaces from Address

  • Add City values to the new table

  • Make all State value upper case

  • Fill in Postal Code

  • Finalize the values
