File formats which are similar become difficult to be interchanged when you want to edit the data stored in them. Just like XSLX, a Microsoft Excel-based application; CSV, 'Comma separated values', is also a simple format used to store numbers and other kinds of numerical data. It can be opened through Microsoft Excel, Open Office Calc or Google Spreadsheet. Files that are stored in the CSV format can be exported and imported from other programs, which are stored in tables. Turn PDF allows you to change the XSLX files into CSV files for easy access and storage. With a single button you can turn all the XLSX files to CSV files and edit them accordingly.
