How can I open a file which contains more than 65 536 rows?

Use this macro from Bernie Deitrick

If you're new to macros:

===========================================================
' Importing a large file into Excel. File MAY have more than 65,000 records
' and will automatically start a new sheet.


Sub LargeFileImport()
'Bernie Deitrick's code for opening very large text files in Excel
'Dimension Variables
Dim ResultStr As String
Dim FileName As String
Dim FileNum As Integer
Dim Counter As Double
'Ask User for File's Name
FileName = Application.GetOpenFilename
'Check for no entry
If FileName = "" Then End
'Get Next Available File Handle Number
FileNum = FreeFile()
'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
Workbooks.Add Template:=xlWorksheet
'Set The Counter to 1
Counter = 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
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

That code is 'limited' to importing text files, correct? And will import
each row of the text file as a single entry into the rows on the worksheet?

Armandc - take note of those limitations. If your desire is to import a
data from an Excel 2007 file with more than 65536 rows of data, you may need
to attack it in a different manner:
Have the person with Excel 2007 save the file as a .csv file.
Download this file from my site (click the link and choose Save) to your
hard drive. Open that file [it does have macros so your macro security may
need to be reset] and follow the instructions:

If you ever need to import a .csv type file with more than 256 columns of
data (but less than a full page of rows) then this other file may help you:
