In Microsoft Excel 97 for Windows, Microsoft Excel 2000, Microsoft Excel 2002, and Microsoft Office Excel 2003,
text files that contain more than 65,536 rows cannot be opened in their
entirety. You cannot open these files because these versions of
Microsoft Excel are limited to 65,536 rows. If you open a file that
contains more data than this, the text file is truncated at the row 65,536, and you receive the following error message:
File not loaded completely.
However, you can use a
macro to open the file and automatically break the text into multiple
Versions of Excel earlier than Excel 97 have a limit of 16,384 rows.
Versions of Excel later than Excel 2003 have a limit of 1,048,576 rows.

The following sample macro prompts you for a text file name, and then opens the
file into memory. If the number of rows is larger than the Excel
worksheet limit of 65,536, the macro breaks the file into multiple
worksheets. This macro applies only to files you saved as text files and
does not apply to any other file formats. The macro does not work with
database file formats.
Note that because this is a macro, using it may be significantly slower
than clicking Open

'required for the macro to run.

The macro does not parse the data into columns. After using the
macro, you may also need to use the Text To Columns
command on the
menu to parse the data as needed.
When you run this macro on a Macintosh, and you are attempting to open a
file that is on the desktop, you must precede the file name with the
Hard disk:Desktop Folder:
where Hard disk
is the name of your hard disk. Note that there is a
space between the words Desktop and Folder.
