Please follow the below approach:

  1. Launch Excel
  2. Set the variable ForumlaText to the formula =COUNTA(UNIQUE(FILTER(A5:A1000000,A5:A1000000<>""))).
  3. Set the clipboard text to the value of the variable ForumlaText.
  4. Activate cell H1 in the Excel instance.
  5. Paste the content from the clipboard into the activated cell in the Excel instance.

Dear @Chetan_Ninghot 

Sorry for my late reply.

Please find here the screenshot of the error (Sorry, the error is in french)

The translation of the error is: "Cannot write into Excel file"

Have you tried assigning formula in clipboard and pasted in  excel cell?

 

For quicker reference:

Instead of ‘write to Excel’

 

Set to clipboard text %Formula%
Then activate the cell you want to paste in

Then Paste cells to Excel

 

Here is mine, and it worked.  Ignore the 'Replace Text', we use commas instead of semi-colons.

Dear @Deenuji 

What do you mean with "Set to clipboard text %Formula%" ?

I'm sorry i'm still a novice in power automate desktop.

Could you please explain a little more how to convert clipboard text to formula?

Hi,

 

Now i know what was going wrong with my formula.

It should be translated to English formula instead of French formula on power Automate Desktop.

Now it works!

Thank you al for your support!
