Hi!

I am going over a very big excel file, and I want to summerise subjects.


I want to go over a specific column of the the whole sheet, and delete all lines which do not include a specific string (say "Brg").
How can I do it ?
I want to go over a specific column of the the whole sheet, and delete all lines which do not include one of X strings.
Example :  I want to delete all lines which do not include one of the following strings : {"Str_1", "Str_2", "String3", "Str4"}.

I want to go over a specific column of the the whole sheet, and delete all lines which do not include one of X strings (but do not delete lines which the cell is Empty).
Example :  I am going over column J, and I want to delete all lines which do not include one of the following strings : {"Str_1", "Str_2", "String3", "Str4"}, BUT I do not want to delete lines in which the "J cell" is empty.
How can I do it ?

After I delete all "undesired lines" I want to summerize Column K and Column M.
How can I do this ?


I am working with Office 2007

Thanks

In a new column...

1. =ISNUMBER(SEARCH("Brg",j1))  copied down

2. =ISNA(MATCH(J1,{"Str_1","Str_2","String3","Str4"},0))  copied down

3: =AND(J1<>"",ISNA(MATCH(J1,{"Str_1","Str_2","String3","Str4"},0)))  copied down.

The TRUE results would be the rows to delete.

I am not sure that I had understood.
1) Does this automatically delete the "undesired lines" ?
2) what is "copied down" ? Is this a valid Excel command ?
3) I was looking for a Macro.
4) I would like to look at the spreadsheet after the lines had been deleted.



Thanks

My solution is a formula solution.

You enter the formula in the first row of a free column, then copy it down the column.

You can then use Autofilter to filter for TRUE in that column and delete those rows.  Then switch off Autofilter to see the remaining rows.

Macros are out of my jurisdiction, sadly :(

Just one thing : How do I use Autofilter ?

while you are in a cell in your table, go to Data and select Autofilter (the large Funnel icon).

You should see drop down arrows in the top row, go to the column with formulas.  Click the drop down arrow and check only the TRUE choice.

Now select all those rows and delete them.

Then reselect the filter and check ALL.

Thanks,

it almost works.....

I have two problems :

1.

Simple problem : when I try to summerize column M, is summerises also the hidden lines....
How can I summerize only the non hidden lines ?

2.

The file becomes much larger than the original file because of the "copy down step".
Here is how I "copy down" :  
Press Ctrl+C
go down one cell
Press Shift+End keys
Press down key
Now all of a sudden I have a milion lines (instead of the original 30,000 lines)
The problem is that now calculating the formula and/or saving the file takes a lot of time


Thanks

After you enter the formula in one cell copy it, then select the next cell down, go to the bottom of the sheet where your last row is, then hold the SHIFT key down and select the bottom cell, then copy.

You can then copy the column, right click, select Paste Special, then Values, this will remove the formulas.

Then filter.

If you are not deleting the "TRUE" rows, you can use SUBTOTAL() function.

e.g. =SUBTOTAL(9,M:M) will sum only the visible cells.
