My words from my mind

Tableau has an awesome feature to allow users to export the processed data into crosstab, or I would say Comma Separated Value format.
We use Tableau to help us visualize data into graphs and charts. And our raw data is often messy and huge and doesn’t really make sense in that granular state. So the charts and graphs are really much better to look at. And even though some users are happy enough by looking at charts, some others find it important that we can get the post-calculated raw date, i.e. the numeric equivalent of the given chart.
But when it comes to a grander scale of a few thousands rows of records, The Export Crosstab to Excel just doesn’t work well. It took a very long time to work, and that if it works at all.
So, instead of exporting it to Excel, use Copy -> Crosstab function. This function is surprisingly much faster than exporting to Excel.
As a comparison, exporting 50,000 rows to Excel will take forever, and never but copying the same 50,000 rows to clipboard only takes 5 seconds.
