Word will print the address on each envelope. How to edit?

Merge with Word mail. The working principle of mail merge is to read the data from the data source file through the main file and merge it into one file for printing. Data source file: it can be a table of Eecel or a table of Word; Master file: the format of the text to be printed on the envelope is designed here. The key contents, such as name and address, are obtained by reading the data source file, so it is not necessary to input them one by one. Specific operations can be searched online.

Answer supplementary questions:

Then you can use these three columns to build a data source table. The first column is the company name, the second column is the customer address, and the third column is the postal code and city.

When inserting fields in the main document, you don't need to design a table. When inserting the field directly in the first line, select "Company Name", and select "Customer Address", "Postal Code and City" in the second and third lines respectively. Then set the font and alignment, and it's OK.
