Validate Excel with text in text file

[Vinci141]

Hello,

I am looking after ways to validate excel cell content which is mentioned in a text file.
Text file also contains predefined values in those cell address
Example
text file contains below
r1c1="Project_Name"

here, r1c1=Row 1 col =1 of excel sheet. It must contains "Project_Name" as content.

I assume this is going to be very large and thus, any formulae to achieve shall be thankful.
Please advise.

Thanks
