@BhargaviB3067 You cannot directly in a RD but you can filter the data in the clipboard and store it without the HTML tags using the function, so by the time you run the report, there will be no tags in the data.
If you need a function to use directly in RD, please use pxReplace and replace <(.|\n)*?> with " ", again this is a workaround suggested in above post with a screen shot for reference if you need.
@KOMARINA I have tried pxReplace and replace <(.|\n)*?> with " " in Report definition, but didnt work. Report fetching data with Html tags. Attached sceenshots with my results
And I cannot use pzUnescapeHTMLSpecialChars since I fetching report for existing cases.
