Dear Forum members,
I have to process one datatable which is having more then 2 lakh rows.
I have to visit each cell.
But for each row is taking many hours to process whole data.
Is there any way to process it in minutes ?
Any help will be appreciated.
Regards,
Sahil Garg

Actually can’t use external activity
Hi @Sahil_Garg
For faster approach use the below code in invoke code with dt1 datatable as argument type in/out
dt1.AsEnumerable().ToList().ForEach(Sub(row)
row(“Date”)= NewDatestr)
Try this
Mark it as solution if it resolves ur query

Hi Nived,
Your solution worked but it is still taking time to convert all.
Do you have any query for find and replace in data table without opening excel.
Check below post for connecting excel as a database
Once you finished your configuration, then you can use SELECT / UPDATE Query with Execute Query activity
Hope this helps you
Thanks
