Are you saying you wish to copy data from a different spreadsheet into a web ADI spreadsheet? If so then yes, that is entirely possible, you just need to make sure you've inserted enough blank rows. I'd paste values as well just to be sure.
Yes i have enough rows added in ADI Sheet and now just want to copy from other sheet, Please advice CTRL+C and CTRL+V not working on ADI Sheet.
Make sure the excel columns format are identical to the format specified in the WebADI template (i.e. text, number, date ...etc.)
Ensure you "Paste Values" too.
