Hello community,

I have a Payload of 100 variables.  
i can’t change them manually  
where i need to do a mandatory check for each feild like 100 times.  
can i do the payload as centralised and run some iteration where each time it will comment the specific field i want, and next it will re-add the field and comment out the next field?  
Please help me

Hi @daiva001. You can present this payload data as a CSV or JSON and use the collection runner to run a request in each variable iteration.

You can provide a “data file” to the runner, and every request will run against each row or entry in the data file. You can learn more [here](https://learning.postman.com/docs/collections/running-collections/working-with-data-files/)

Hey @gbadebo-bello,

Thanks for the Response.  
But my requirement is different  
I will run the collection and the Collection responses need to Paste into Excel Sheet  
Where one field one one Field has to commented. For Ex:  
Paylod  
{  
A:Apple,  
B:Ball,  
C:cat  
}

First time it has Comment out //Apple and send the remaining request  
Next add back the Apple and //Ball like this it has to Work.
