Word includes a powerful feature called Mail Merge that allows you to combine a document with data from a data source to create individualized documents. Once you have created your main document and your data file is attached, it is a good idea to run a final check by comparing your data file with your document. To do this, start by opening your main document. Make sure the Mailings tab of the ribbon is displayed.
In the Preview Results group click the tool called Check for Errors or, in earlier versions of Word, called Auto Check for Errors. Word displays the Checking and Reporting Errors dialog box. (See Figure 1.)
Figure 1. The Checking and Reporting Errors dialog box.
Select the radio button that indicates how you want Word to check your data file. The selection you make depends on how confident you are in the quality of your data file. If you are fairly confident in its quality, accept the default and allow Word to show you the few errors your file may contain. If you aren't sure about the quality of your data file, then select the first option to simulate a merge and report the errors in a new document.
