But if we run the split() function on this file then it won’t care for any such quotes. In the above CSV file, it can be seen that the first field has a comma within itself, hence closed within quotes.
It just cuts where it finds the separator character.įollowing is a CSV file which has a comma within the quotes: In such a situation if a split() function is used, even if within quotes, then it will separate the values each time it gets a comma as a delimiter, because split() function does not care about the quotes, nor does it understand anything about CSV. Sometimes there might be a file that has a comma within the fields of a string that if removed will change the meaning of the data or make the record useless.

Following is a code for split() function to separate the strings stored in the new.csv file with the use of a delimiter: Let’s get to an example to get a better understanding of the topic. Step 3: Print out all the values one by one to get the result Step 2: For each line, store all value in an array. Note: If $words is printed then result will be "Sugar" as array indexing starts from 0.įollowing steps are followed to split lines of a CSV file into parts using a delimiter: The array will be filled with 3 values: “Johny”, “loves” and “Sugar”. If Input string is passed to split function = split("", $s) Returns: an Array of string elements separated by _delimiter_ _string_: From which values are to be extracted _delimiter_ : Separator value between elements The first is a delimiter, the second is the string that needs to be split. This delimiter can be any character as per user’s requirement, but generally, we take comma as a delimiter. Split() is a predefined function in Perl which is used to separate a string into parts with the help of a delimiter. For Extracting every value from a specific line, we are going to use the split function. Perl also supports the manipulation and creation of these ‘csv’ files by extracting values from the file, manipulating these values and restoring them into the file. These files can be easily opened in Excel and can be manipulated with the use of any suitable software.
