Excel Workbooks with external workbook links loading extremely slowly
Using Excel via Office 365, I have noticed a dramatic increase in the amount of time required to open any member of a group of files, each of which have links to other workbooks. These are files...
I fixed this issue for myself by changing from each cell having an individual formula, to the sheet using an array instead.
You do this by selecting all of the cells you want to take from the other document, going to the other document, selecting all of the data on that side, then hitting Ctrl + Shift + Enter.The formula will end up looking like this
{=path/[data_document.xlsx]Sheet1'!A1:Z500}
FAIR WARNING: If you do this over empty cells, they will become 0 instead of empty, so if you have code that expects a string, you will get a data type mismatch error.
Whatever the problem was it seems to have been resolved this morning. I tried to run my macro last night and it took 7 hours to run. This morning I made some changes to the data and ran the macro again and it was done in 5 minutes, same as it has been for the last 5 years.
- Same here, problem has magically resolved itself. Guess we'll never know what happened....
