Reading CSV file in Postman

CSV:

a,b,c
1,2,3
1,5,6
2,4,6

CSV parse output:

Approach 1: store CSV content as an environmental variable

Just copy the CSV file content and create an environmental variable and paste the content inside it

Then in test or pre-requisite step:

console.log(pm.environment.get("data"))
const parse = require('csv-parse/lib/sync')
//Environmental variable where we copy-pasted the csv content
const input =pm.environment.get("data");
const records = parse(input, {
 columns: true,
 skip_empty_lines: true
})

console.log(records)

Approach 2: Passing the CSV content to an environmental variable through Newman (Powershell):

Then in test or pre-requisite step use the same code as above:

> $a= Get-Content -raw .\1.csv
> newman run .\test.postman_collection.json -e .\test.postman_environment.json -k -r "cli,htmlextra" --env-var data=$a
