Extracted Value From App changed to digit and want to send it to excel file

I got data from my app , and converted into number format after removing the text part of it. I want to write that number into the excel file I have on a folder outside of my project. Can anyone help with this? Here is the screenshot for your reference. Thanks a lot!!

Could use write cell workbook activity to write it in excel.

Two points

  1. I use modern design activities
  2. I do not see ‘Write cell workbook’ in the activities list

Am I missing something?

I am using modern activities too.
could you please update excel packages in your manage packages window?
