Delete the string after the delimiter in excel

问题

I have simple problem. I was analyzing some data and came up with this problem.

Below is my value in a colomn:

www.mysite.come/api/Customer?id=12333&name=jack
www.mysite.come/api/Department?id=52365&name=COP
www.mysite.come/api/Customer?id=13333&name=mathew

etc

I want to filter this data something like this

www.mysite.come/api/Customer
 www.mysite.come/api/Department
www.mysite.come/api/Customer

Please help me with this.

If its just as simple as removing everything after, including, the ? then this will do it:
=LEFT(A:A,FIND("?", A1)-1)

Edit: If you want to catch the #VALUE! error when there is no ? simply use IFERROR:
=IFERROR(LEFT(A:A,FIND("?", A1)-1), A1)

Example rows:

www.mysite.come/api/Customer?id=12333&name=jack
www.mysite.come/api/Department?id=52365&name=COP
www.mysite.come/api/Customer?id=13333&name=mathew

Output:

www.mysite.come/api/Customer
www.mysite.come/api/Department
www.mysite.come/api/Customer

I think you need to use a combination of FIND and LEFT.

For example (where A1 contains your original value)

=LEFT(A1, FIND("?", A1) -1)

The significance of your mention of filter is not clear to me but you might copy your data into another column, select the latter column and with Find/Replace Find what:

~?*  

Replace All.

Its a good idea to handle when when the column doesn't contain the "?". To do this use the ISERROR() function as follows:

=LEFT(A2, IF(ISERROR(FIND("?",A2))=TRUE,LEN(A2), (FIND("?",A2)-1)))
