Hi,

I have a very long Excel spreadsheet, in excess of 13,000 rows,
generated from a network capture. The original datasheet has multiple
columns, but I’m only interested in two:

* Column G: which contains attributes, which are to become the column
headers in the new spreadsheet (e.g. length; timestamp; source address
etc.)

* Column I: which contains data (the variables) from each frame (e.g.
64; 000897; 10.10.0.4 etc.)

Manual transposition works, but is unfeasible for this amount of data,
I’ve seen various posts on automated transposition but I have an
additional issue in that each frame is an inconsistent total length.
That is Frame 01 would be transposed from A1:P1, but Frame 02 would go
from A2:AA2, which appears to be an issue for most VBScripts I’ve
seen. There is however some consistency in that the data I which to
use consistently runs for 46 rows, and the start of the next frame is
flagged by the start attribute “num”.

Therefore the attributes are transposed from Column G to row 1, only
once to form the headers.

IF Field = "frame.number"
THEN transpose to column A;

IF Field = "len"
THEN transpose to column B
AND rename "frame.length";

IF Field = "frame.time"
THEN transpose to column C;

Etc, etc.

And the variables are transposed under the relevant Attribute (e.g.
column header):

IF Field = "frame.number"
THEN transpose from column I to
column A row 2;
REPEAT for row 2 +n
UNTIL END;

IF Field = "len"
THEN transpose from column I to
column B row 2;
REPEAT for row 2 +n
UNTIL END;

IF Field = "frame.time"
THEN transpose from column I to
column C row 2;
REPEAT for row 2 +n
UNTIL END;

What I then end up with is a new spreadsheet that has:
frame.number frame.length frame.time Further
Attributes ........
1 60
000000000 ..........
2 64
000000002 ..........
3 62
000000004 ..........
Further variables
.......

Does anyone have any suggestions as to the best method to attack this
problem?

Thanks

Doug

This will give you the column length for each column

for i =cells(1,columns.count).end(xlToLeft).count
lastrow=cells(rows.count,i).end(xlup).row
msgbox lastrow
next i

for your need to get the last column
for i =cells(columns.count, "a").end(xlup).row
lastcol=cells(i,columns.count,i).end(xltoleft.row
msgbox lastcol
next i
