Powershell script to remove double quotes from CSV unless comma exists inside double quotes

Question

I have a .csv in the following file format:

In: "bob","1234 Main St, New York, NY","cool guy"

I am looking to remove double quotes that don't have a comma inside:

Out: bob,"1234 Main St, New York, Ny",cool guy

Is there a way to do this in Powershell?

Answer 1

Adapting the code from "How to remove double quotes on specific column from CSV file using Powershell script":

$csv = 'C:\path\to\your.csv'
(Get-Content $csv) -replace '(?m)"([^,]*?)"(?=,|$)', '$1' |
    Set-Content $csv

The regex (?m)"([^,]*?)"(?=,|$) is matching any " + 0 or more non-commas + " before a comma or end of line (achieved with a positive look-ahead and a multiline option (?m) that forces $ to match a newline, not just the end of string).

See regex demo

I don't know exactly what the rest of your script looks like. Try something along these lines though

(("bob","1234 Main St, New York, NY","cool guy") -split '"' | 
  ForEach-Object {IF ($_ -match ",") {'"' + $_ + '"' } ELSE {$_}}) -join ","
