Report with Conditional formatting takes long time to export to Xls format
I have a report with conditional formatting applied for 6 fields. The report fetches about 6k rows and running report takes few seconds only. Whereas exporting it to xls takes more than 10 minutes.
If I remove the conditional formatting from the report, it takes only 20 secs to export. So I came to conclusion that conditional formatting is causing slowness while exporting to excel.
Is this expected behavior ? How can I improve the performance when report has conditional formatting applied?
