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 proves useful when you need to write out data for another system to read, or even when you need to produce HTML files.
There are two basic scenarios when reading from text files. If the 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.
