The performance of exporting data from a nested view is absolutely horrible. The nested view is a very valuable tool to see your data grouped in various ways, but the export function is almost unusable - even when you only have 50,000 rows of data.
It’s there anything specific you’d like it to look like?
Currently the export works well if you want to drop out a lot of data and manipulate it further with a pivot table etc. I wouldn’t want to lose that completely.
My assumption is that like me, you want an option to export it and keep the layout as it is in the grid.
It’s this what you’re proposing?
