Why You Must Validate Data

basic data analytics1Before you analyze data, you must first validate it.

Otherwise, your analysis may not be accurate, and you may miss some important insights or errors.

This post is part of the Excel: Basic Data Analytic series.

Before analyzing your data, you need to check the following:

  • Duplicate transactions do not exist.
  • Required fields/key fields do not contain blanks, spaces, zeroes, unprintable characters, or other invalid data.
  • Date fields contain real dates, and the range of dates is appropriate.
  • Amount fields don’t contain inappropriate zero, positive, or negative amounts, and the range of values is appropriate.
  • Each field is stored in the correct format. This prevents data from being converted on the fly into something else unexpectantly (e.g., user ID JUL15 becomes 15-Jul).

Excel: Text to Columns

basic data analytics1Excel’s Text to Columns function allows you to separate pieces of data in a single column into multiple columns.

This function helps when key data is buried in a field with other information and you need to extract the key data into a separate column before you can analyze it.

For example, you obtain a list of email addresses, and all you want are the user IDs. Or you get a list of servers, and the server name is server.domain.com, and you need just the “server” name. Or you need to separate LastName, First Name into separate columns. That’s where Text to Columns saves the day.

This article is the fourth post in the Excel basic data analytic series.
