Checking Your Data File

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, simply open your main document. The Mail Merge toolbar should be visible near the top of the screen.

Near the middle of the Mail Merge toolbar is a button with a check mark on it. Click your mouse on this button, and your data file will be compared against your master document to ensure that all your fields are correctly formatted and accessible. If Word encounters any problems (such as a missing data field in your data file), it will notify you. This allows you to correct the problem before actually trying to create your final merged documents.
