Hi All,

I have a workbook with a lot of array functions. To give an idea:
- 17 sheets of which 15 with about 150 array functions per sheet
- 1 sheet contains the raw data, 10,000 rows
- I have to use array functions because several conditions have to be
checked

It is all working fine, the only thing is that it takes 30 minutes or more
to recalculate the workbook. So, you can imagine that I try to avoid
recalculations as much as possible.

Does one have some good tips to speeding up Excel?

With kind regards,

JP
