Microsoft Excel VBA and Macros (Office 2021 and Microsoft 365)

Chapter 19

Text file processing

In this chapter, you will:

• Import from text files

• Write text files

VBA simplifies both reading and writing from text files. This chapter covers importing from a text file and writing to a text file. Being able to write to a text file is useful when you need to write out data for another system to read or even when you need to produce HTML files.

Importing from text files

There are two basic scenarios when reading from text files. If a file contains fewer than 1,048,576 records, it is not difficult to import the file using the Workbooks.OpenText method. If the file contains more than 1,048,576 records, you have to read the file one record at a time.
