What process is used to insert variable information into a standardized text document?

Mail Merge is the correct process for inserting variable information into a standardized text document. This technique allows users to create personalized documents by combining a template document, which contains fixed text, with a database or list of variable information, such as names, addresses, or other specific data fields.

During the mail merge process, the standard document can be efficiently populated with different sets of information, allowing for mass customization without having to manually modify each individual document. This makes it an invaluable tool for creating items such as personalized letters, labels, and envelopes.

The other options, while related to document processing, do not specifically pertain to the technique of merging variable data into a standardized format. Document automation generally refers to broader systems that manage document creation and lifecycle, data fusion involves integrating data from different sources, and text enhancers typically refer to tools that improve the quality or readability of text rather than inserting variable data into templates.
