Hi @Ahmedmuz
You can try this approach of pasting the excel to outlook mail. Here it will be a background process of converting the excel table to html table and then appending to the mail using outlook mail actions
The overall flow of excel table to html table is like below


Here i had used the input as excel file

Output i got from this flow is a table which can be added in email (html format)

This is the html format table.
in the flow screenshot, you can see that i am writing the final_text variable to a html file. You can use the same variable in the send outlook mail action like below

You need to enable the option to write the body as html
This way you can send the mail with table
Let me know if you have any questions
Kindly mark it as solution if it helps 🙂
Thanks & Regards,
Nived N
