Inserting new rows in Excel model takes extremely long

Hi everybody,

so I'm currently building this real estate project model for one of our clients. Unfortunately, it turned out to be a lot more complex than initially thought as it projects both the client's relatively complex operations, tied to specific buildings, and the real estate development project again connected to the client's operations and vice versa.

It's a quarterly model with a span over 30 years, and makes heavy use of INDEX/MATCH and other array functions. Nonetheless it calculates rather quickly even with the necessary circular references switched on at a 1,000 iterations.

The problem is that inserting new rows takes extremely long (>1 minute each). I thought that this might be due to the circular references and auto calc mode. But it also happens when the circular references are switched off and calculations are set to manual.

Has anyone else encountered the same problem?

There's some conditional formatting. But nothing too crazy. I'm just tracking whether there are capacity changes to the previous quarter, and the usual TRUE/FALSE color changes.

Is it possible that it's just because of the size of the model (+5,000 rows)? The datatables are also not working correctly, regardless of calc mode.

 

So killing the conditional formatting and styles definitely speeded it up.

What's funny though is that now it's also faster with older versions of the model which still do have the conditional formatting and the styles. That's pretty weird.

But anyway, it did the job. Thanks!
