Filter / Report Top 10 Values with identifier into new spreadsheet / table / report style

Hi Everyone,

I have a load of Census data in an excel format. It has ancestry values for each postcode (2000+) and I want to get the TOP 10 Values from each (with their identifier) - so for instance;

Postcode 2000 - Top 10 would be 1. 4000 (chinese) 2. 2131 (indian) 3. 2000 (Vietnamese) ETC ETC ETC and so forth.

Would this be possible? I Know it's not an easy task and sounds like a big job, But having to manually do this is.. well.. a much bigger job.

In essence it would look like postcode + Cell identifer + cell value for each postcode. I have attached the test data.

Regards,

Steve
