How To Reduce Unused Rows In Worksheet; Make File Smaller

I have a file that became too big due to phantom bloat, unused range saved by Excel and all that kind of reasons. Thank to previous posts on that board tackling that issue, I was able to find how to proceed to reduce the file back to its normal size.
But I did so in a beta file (test file). The real file has become so big (103MB!) that Excel cannot even open it anymore! The file contains archive info that we do not have anywhere else.
Is there anyway then to open the file or to reduce its size without opening it (through magics...)? I just honestly don't know how to retrieve that info before deleting that file.

Thank you very much for your help.

I have a large worksheet. Over 20,000 rows. I want to split every 900 rows into new worksheets. I need each worksheet to be 900 rows or less when done. Any macro would be helpful.

Hi all.

I have set up a workbook that is sent out to lots of different users. They each keep and use their own copy.

I have set it up so that everything looks OK and is visible on MY screen, but I'm conscious that some users may have different screen sizes, different toolbars set up, and so on, which might make some parts not immediately visible to them.

I have set up an auto-execute macro which automatically sets the zoom factor to best fit, for several of the worksheets, and this works fine.
Here's the code that does it.
Code:

Sheets("WELCOME").Select
    Range("A1:N18").Select
    ActiveWindow.Zoom = True

By repeating this code for each worksheet, I can make each one be zoomed just right.

However, the file contains 8 sheets that are all identically laid out, except the number of rows is different.
What I want to do is go to the worksheet that has the largest number of rows (it's always the same worksheet, so I know which one it is), set the zoom factor for THAT worksheet (which I can do, and it always has the same number of rows), and then take THAT zoom factor, whatever it is - and it will vary depending on the user - and apply that to the other worksheets that have a similar layout.

I could just go through each worksheet and zoom it automatically, but that would mean that some of the sheets looked very large, others very small, and I'd like them to have a consistent appearance.
I could also specify a range on each worksheet that was similar to the appropriate range on the longest worksheet, and zoom that automatically, but that's not ideal either, because some of the row heights vary from sheet to sheet, and again I'll end up with different font sizes.

Anyone know how to do this ?

I'm unable to group/ungroup rows or columns on an excel worksheet that was
emailed to me by a co-worker. It's an existing file so I don't know what
restrictions were placed on the workbook. What can I do to fix this problem?

Hi peeps

I want to combine data from several worksheets into one worksheet.

For example, I have data in Sheet1 (Columns A,B,C), data in Sheet2 (Columns A,B,C), data in Sheet3 (Columns A,B,C) all with varying amounts of rows. (All the rows contain text data).

I need to combine all of the data from the 3 sheets into a single sheet, Sheet4 (Columns A,B,C), eliminating the empty rows.

I've been looking into this for a while, and can't find anything that really helps. Anyone got any pointers of what to look into?

Any help will be beautiful.

Cheers
