Does your spreadsheet works with current version of Excel Activities?

Hi Vvaidya, yes, i have conducted test like read range, write cell, append range. and writing the output in another excel file.


I had the same error.
My process looked as follows:

  1. connect to DB
  2. select query from table
  3. disconnect from DB
  4. connect to DB
  5. insert into DB table
  6. disconnect from DB

I solved it by removing the first disconnect and the second connect activities.
The process looks as follows now:

  1. connect to DB
  2. select query from table
  3. insert into DB table
  4. disconnect from DB

Hope it helps people with the same issue :slight_smile:



I found the error but sorry never came back to post it, it has to do with the headers.but the connection fix you are posting might help, I mark your answer as solution, thanks buddy.

Could you send the right program, when putting the headers, it gives me another error.
