Text files that are larger than 65,536 rows cannot be imported to Excel 97, Excel 2000, Excel 2002 and Excel 2003

Summary

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 worksheets


Notes

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.

This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure. However, they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. 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 on the File menu.

'All lines that begin with an apostrophe (') are remarks and are not
'required for the macro to run.
   Sub LargeFileImport()

'Dimension Variables
Dim ResultStr As String
Dim FileName As String
Dim FileNum As Integer

'Check for no entry
If FileName = "" Then End
'Get Next Available File Handle Number

'Open Text File For Input
Open FileName For Input As #FileNum
'Turn Screen Updating Off
Application.ScreenUpdating = False
'Create A New WorkBook With One Worksheet In It

'Set The Counter to 1

'Loop Until the End Of File Is Reached
Do While Seek(FileNum) <= LOF(FileNum)
'Display Importing Row Number On Status Bar
Application.StatusBar = "Importing Row " & _
Counter & " of text file " & FileName
'Store One Line Of Text From File To Variable
Line Input #FileNum, ResultStr
'Store Variable Data Into Active Cell
If Left(ResultStr, 1) = "=" Then
ActiveCell.Value = "'" & ResultStr
Else
ActiveCell.Value = ResultStr
End If

'For Excel versions before Excel 97, change 65536 to 16384
If ActiveCell.Row = 65536 Then
'If On The Last Row Then Add A New Sheet
ActiveWorkbook.Sheets.Add
Else
'If Not The Last Row Then Go One Cell Down
ActiveCell.Offset(1, 0).Select
End If
'Increment the Counter By 1
Counter = Counter + 1
'Start Again At Top Of 'Do While' Statement
Loop
'Close The Open Text File
Close
'Remove Message From Status Bar
Application.StatusBar = False

End Sub
Note 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
Data 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 following
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.
