Incorrect parsing of wrapped values when the new line is right after the starting quote

[symbianm]

Background Information

• Module Version: 4.1.0
• Node/Browser Version: node v18.17.1

The issue I'm reporting is with:

• [ ] json2csv
• [x] csv2json

I have...

• [x] searched to see if an issue has already been reported.
• [x] verified that my JSON/CSV data is valid (using something like http://jsonlint.com or https://csvlint.io/).
• [x] tried upgrading to the latest version of json-2-csv (since the issue may already be fixed).

Expected Behavior

Quoted values split across multiple lines should be correctly parsed.

Actual Behavior

The parser behaves incorrectly when the new line is right after the starting quote.

Data Sample

CSV:

"User","Rental","City","State","ZipCode","Lead","Created","Qualified","Notes","Status","Details","Rating","Feedback","External Id"
"Leasing  Team","xxxxx North Sabre Drive","San Tan Valley","AZ","85142","AaronMiriam McAlpine","10/1/2023 5:25 PM MST","10/1/2023 5:27 PM MST","","Confirmed","10/1/2023 5:30 PM MST","5","
Layout was nice. Landscape needed work. But nice otherwise.","a001K00000vxWbxxxx"

Code Example

const fs = require('fs');
const { csv2json } = require('json-2-csv');

(async () => {
  const contentString = fs.readFileSync('test.csv');
  const jsonData = await csv2json(contentString.toString(), {
    parseValue: (fieldValue) => fieldValue, // stop converting values
  });
  console.log(jsonData);

  // Result
  // [

Thanks for reporting this @symbianm! I can confirm that this was a bug that was present in the CSV parsing logic when an EOL delimiter (typically newline) appeared inside a field (typically quotes) delimited value. This issue is resolved now in version 5.0.1. Please let me know if you run into any other issues.
