CSV File Manipulation

[Azeem Mohammed]

Hi,

Can someone tell me how CSV files are manipulated in Java? And is there a way that new columns can be created in a CSV file with excel formulas using Java ?

Thanks,
Azeem

I think we are well aware that CSV file is a plain text file with comma separated values in it. So its just simple plain text; formatting facilities, formulas etc are not available. Spreadsheets like excel allows to view a CSV file in a tabular format. So what ever jazzy facilities you see in excel are not owned by CSV.

Now you know that CSV is a plain text , you know how to handle a plain text file with a comma delimited tokens (CSV file processing can be more complex depending on the type of data you have For example handling embedded commas , quotes etc makes it complex if your data demands for it).

Now if you dont want to create a CSV , but a spredsheet with jazzy features , then go for tools like Apache POI.

The https://coderanch.com/how-to/java/AccessingFileFormats page points to a number of libraries that can be used to manipulate CSV files, but I think they're mostly about reading and writing, not manipulating.
