Mail merge is a software function in Microsoft Word that allows the production of multiple documents with the same formatting but varying content. It uses a Main Document and a Data Source to replace Merge Fields with the corresponding data from the Data Source.
Mail merge is a software function used in Microsoft Word to produce multiple documents that have the same formatting, layout, text, and graphics, but with certain portions varying. It requires two files: the Main Document and the Data Source. The Main Document contains the information that does not change, while the Data Source contains the variable/changing information in the form of fields. When the Main Document and Data Source are merged, Microsoft Word replaces each Merge Field in the Main Document with the data from the respective field in the Data Source.
