VBA to remove rows based on column colour

Contributor

Hi there,

 

I have attached an example spreadsheet which I could do with some help on please.

 

I am trying to acheive the following:-

 

caluclating the average of each column zz, zy, zx & zw. I want to caluclate this within a section.

 

The section is determined by 2 rows of blue. Where there is 1 row of blue this can be disregarded.

 

Ideally, each time there is a double row blue, this is a new section, which would have a section name.

 

What would be perfect, is if there was a way to return a result which just has secion name, and the 4 averages for each section.

 

I hope this all makes sense.

What you're asking makes sense. What you have as a spreadsheet, however, raises a number of questions.

 

I've given you a solution. But I made some modifications to the way you arrayed your data, AND to the nature of the data. 

  1. Instead of separating sections by headers, I identified the sections by a new column containing the differentiating label.
  2. And instead of texts that look like numbers but aren't, I used the VALUE function to convert them to values. It's a lot easier to calculate averages (well, for that matter, to do ANY kind of calculation) if you actually use numbers. I'm not sure what the source is for these, but I left them as is and just created adjacent columns with the text converted to value.

The solution I offered uses a new function, FILTER, to select for the calculation only the rows that meet the criterion of belonging to the designated group. Here's the formula:

=AVERAGE(FILTER(G$3:G$47,$A$3:$A$47=$M3))

Where $G3:$G47 is the column containing the values for ZZ (I designated it as ZZ2)

$A$3:$A$47 is the column containing the group designation

$M3 is the cell containing the criterion for the filter......

 

You do need the most current version of Excel for FILTER to function. If you don't have that, I recommend updating your system. This is only one of a number of really useful new functions.

Hi Mathetes,

Many thanks for taking the time to look at this for me and help. This is awesome and is doing exactly what I need it to do.

I million and 1 thank you's.

Best regards

You're very welcome.

 

I'm glad my response made sense and that you're able to use FILTER.
