A comma-separated values (CSV) file is a delimited text file that uses a comma to separate values. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. Designed with simplicity in mind, XLS to CSV Converter can only perform one task: that of extracting the contents from the input Excel (XLSX or XLS) files, then transfer them to newly created CSV files. In other words, you just have to select the input Microsoft Excel files and choose a folder to export them to CSV format, all with just a few clicks.

The best part of the program is that the conversion is done completely offline. You are the only controller of your private data. No XLS, XLSX or CSV document is sent to internet in any case.
