Replacing a list of values in just one column with certain text

It would help us if you were able to post a sample of your before and after scenarios, then we could take a look for you.

Ok, so I added a link to the worksheet, above. The other thing I didn't mention, which I will be able to do manually in one fell swoop, is that the second row is just the headers from the download that will be deleted before upload.
There are just so many records, and so many unique values that all need to be converted, I am having a hard time understanding how to do this easily.
The 240 unique Categories are pasted here far to the left. Those, also, I do not want to show within the sheet as they are. But, they are what I need to include in a macro.
Does what I need to get done seem straight-forward to you.

Hi
Sorry but a template does not really help. If you can post a sample of the raw data (before scenario) and the required result (after scenario) I can then make a call as to whethere I can help you or not. Without that info I can't see clearly what you are looking for.

Okay, I actually want to keep my values confidential.
Would there be a straightforward way to:
1300 rows of records, each with one of 240 subcategories, and change just the category ID columns from text to ID
How to keep that a-z list of subcategories out of the template.
At this rate, I'm guess that a find and replace for just just those columns. A separate operation for each of the 240 subcategories

Hi
I fully understand why you want to keep data confidential. However for us to be able to help you you need to help us.
Even if it is dummy data.

Ok, So Now you should see this pretend template that I uploaded. The list of categorys/subcategorys and their categoryid/parentid are to the far far right and is much shorter.

Hi
If I understand you correct you have some source data (as per the sample you provided) and you want it imported to your own format, YES?
Please see row 4 for my comments in red to check if my assumptions are correct and answer the questions I have raised in some columns. Then I believe we can get somewhere :-).
Tony

Please help. I don't understand where to find row 4 with your comments. I don't see where you uploaded any attachments.

Hi
Sorry :-( forgot to attach it. Here it is.

Okay, so the column headers for the source data are in row 3.
They all need to be replaced with the column headers in row 1. I am only concerned about the column headers in row 1 for upload.
The source data will have information in each column to where the headings end in row 3, and not all of those will be needed.
I'll simply delete row 2 and 3.
All of the blank headings in row 1 need to be deleted too. It would be nice If I could delete all the columns in row 1 that have blank column headings at once with a macro, as those will correspond to source data values that I do not need.

For this dummy data, I'm only concerned about converting or working with data in the columns that have values includes, and not even all of those.

Hi
Thanks for the clarity. Here is where I am so far. I have renamed the data sheet to "Products" which will hopefully be generic, if you want a different name then let me know. I have produced a macro which removes all the blank columns and renames the headings.
I have replace the original data so you can test the macro. when you open the workbook run the macro called "FormatProductData" and let me know if this is what you are after.
Good luck.
