Hi Team, I am using the `csv` file where I’m putting all data with respective fields. a sample of the JSON response: ```auto "rank": { "id": 0, "description": "OPTAVIA Coach" }, ``` Now one of the values is `"OPTAVIA Coach"` for which I am making the script as ```auto pm.test("data Verification", function () { var jsonData = pm.response.json(); pm.expect(jsonData[0].rank.description).to.eql(String(data.description)); }); ``` But getting error as data Verification | AssertionError: expected ‘OPTAVIA Coach’ to deeply equal ‘OPTAVIA Coach’ Note: observed when string without space of special character, script working fine no issue. Any Solution for this? ---

It might be the way you’re casting it to a string. Why don’t you try taking out the cast? ```auto pm.test(“data Verification”, function () { var jsonData = pm.response.json(); pm.expect(jsonData[0].rank.description).to.eql(data.description); }); ``` ---

Tried but had no luck.Even tried with Number casting too but not working. ---

Hey @aakashjain8693 What does the CSV file look like? Can you add the full response body and not a sample of it please, it looks like something is missing and it would be easy to run it locally it it’s all there 😃 I’m not really sure what this is supposed to be doing in the expect statement: ```auto String(data.description); ``` Have you tried referencing the data in the CSV file like this: ```auto pm.expect(jsonData[0].rank.description).to.eql(pm.iterationData.get('')); ``` [https://learning.postman.com/docs/writing-scripts/script-references/postman-sandbox-api-reference/#pmiterationdata](https://learning.postman.com/docs/writing-scripts/script-references/postman-sandbox-api-reference/#pmiterationdata) ---

Thanks @danny-dainton for the solution. Solution: Basically few string values contains some other characters which were hidden in .csv file but you can see them on atom so just remove them and try again, it will work.
