使用数组作为标准最大大小的自动过滤

Question

So this is kinda a weird one but:

I have an excel sheet with a few hundred thousand rows of customer data. I have a sheet with 70,000 names and addresses to remove from the bigger sheet.

What I've done before with VBA is combine the names and addresses into one column (on both sheets) and then I put all of the combination name+address cells into an array, then use the autofilter with the array of names + addresses. that shows me all of relevant names + addresses.

However I've never had 70,000 rows to get rid of, and I've discovered that the max number of values you can use in filtering with an array is 65536. I imagine this has to do with the fact that 65536 is the biggest int you can have, and the largest number represented by 16 bits, etc...

does anyone know how I can use the autofilter with an array of values that is bigger than 65536?

Answer 1

An alternative solution is to add a new column in your customer data sheet with a countif(), counting how many times the address of the customer data exists in the address sheet. Then filter on the ones with 0 and delete those rows. Sorry for not giving exactly the answer on your question, but this could be a way to go...
