A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I've done just that and got the following response. Looks like a known issue. None of the suggested work arounds work bar refractoring but not always practical. If this issue is known, can I have an update on when this will be fixed? It's a crippling bug.
From XinXin:
Thanks a lot for sending me your file. I looked at your file – yes, scrolling is not smooth on this workbook. There is a known issue in XL2011 – the more rows/data you filter out, the more sluggish you will observe during scrolling. There are a couple of ways to work around the issue:
1. Use table instead of normal range – I resaved your file (attached) in a table.
2. Use binary file format (such as xlsb, xls, rather than xlsx).
3. Try refactor/restructure the file, so that you don’t have a huge data table.
