Trying to remove the value after 3rd comma and the comma as well

a,b,c,d,e,f 
g,h,i,asj,k,l

How do write regex to find the 3 comma and remove ,d and ,asj ? I tried this /(?=(,[^,]{0,3}\n but not able to get it working

You can use

^([^,]*(?:,[^,]*){2}),[^,]*

Replace with $1 to restore the captured Group 1 value. See the regex demo.

Details:

• ^ - start of string
• ([^,]*(?:,[^,]*){2}) - Group 1:
• [^,]* - zero or more chars other than a comma
• (?:,[^,]*){2} - two occurrences of a comma and then zero or more chars other than a comma
• , - a comma
• [^,]* - zero or more chars other than a comma.
