How to work with long number with csv file?

[amnoman]

1. Newman Version (can be found via newman -v): 3.8.0
2. OS details (type, version, and architecture): Microsoft Windows [Version 10.0.15063], AMD64
3. Are you using Newman as a library, or via the CLI? CLI
4. Did you encounter this recently, or has this bug always been there: Always been there
5. Expected behaviour: Suppose to parse the Long number without changing last 3-4 digit with 0.
6. Command / script used to run Newman: newman run "xxxx.postman_collection.json" -n 2 --f testFolder -e xxxx.postman_environment.json -d "TestData.csv" --ssl-client-cert xxxx.crt --ssl-client-key xxxx.key --ssl-client-passphrase xxxx
7. Sample collection, and auxilliary files (minus the sensitive details):

TestData.csv
Iteration, expectedXXX
1,"89111702272002019559"
2, 89111702272002019542

---

when script executed "89111702272002019559" changes to 89111702272002020000 and 89111702272002019542 changes to 89111702272002020000

The same csv file works fine in Postman runner when use with double quotes for Iteration 1 but Iteration 2 that is 89111702272002019542 changes to 89111702272002020000

@amnoman Thanks for reporting this, I was able to reproduce the bug with the details you provided. I'll update this thread when a fix is being worked on.

I've opened a dedicated issue here: adaltas/node-csv-parse#152

Hi @amnoman, we are now actively trying to resolve this issue, as a temporary fix you can quote numbers within a single quote '89111702272002019559' instead of double quote, in newman to preserve the number as a string and not loose precision.

The issue is the underlying csv-parse library which newman uses to parse csv files, for which we have raised an issue at adaltas/node-csv-parse#182

@amnoman a fix has been added in #1609 which will be rolled out with the v4 release.

You can test this using v4.0.0-beta.2.

@amnoman This has been fixed in Newman v4.0.0.

I am facing this issue. I am on Postman 7.9.0. I am trying to read 19 digit number from csv file. But it rounding the number.
