What would the regex be for matching the first column header in a csv file?
id,field1,field2
1,n/a,n/a
2,n/a,n/a
...
I just safely want to match id

What language/tool are you using? Regex can be different depending on flavour.– TotoMay 12, 2022 at 18:46

@Toto the java 8 version, so the accepted answer would then be "^([^,]*)"g– ZimbabalubaMay 13, 2022 at 8:42

^([^,]*)/g
If you want to test on https://regex101.com/
- ^ = start at the beginning of the string
- [^,] = match anything except a comma
- ([^,]*) = get everything from the beginning of the string to the comma
- /g = don't return after first match
