Current code takes my laptop about 120 second to run and only needs to loop across 6 worksheets. In the actual worksheet which has +20 tabs to loop through, it's taking about 350 seconds and I'm still missing 80% of the input data so would estimate it will end up taking >10mins.

Would anyone have any suggestions on how I could make this code more efficient to significantly speed it up? In the current format with limited sheets, I'd hope for it to take <30 seconds. Maybe something to do with arrays instead of constantly reading from the sheet (I tried it but it ended up taking longer so don't know what I did wrong!).

Code is also as below for those who wouldn't need to access the sheet:

VBA Code:

```
