I\'m working in a web application separated in blocks and I\'m getting a CSV object from a work mate of mine which I must convert into XLS to be passed into an Excel Process
Does the output need to be in the legacy XLS format? If XLSX is acceptable, EPPlus is a great .NET library for writing spreadsheets. The older excellibrary can produce XLS files.
Only a few lines of code should be necessary for parsing the CSV file (just be careful of double quotation marks) and writing the output spreadsheet.
