CSV Document Format CSV Converter
CSV is a type of file for saving spreadsheet data which is recognised by almost all spreadsheet programs. CSV stands for ‘comma separated values’, and if you open a CSV file outside a spreadsheet program, you will see plain text with the data separated, usually by commas, semi-colons, or quotation marks. If you open that same CSV file in a spreadsheet program like Microsoft Excel, Apple Numbers, Google Sheets or LibreOffice Calc, each separated piece of data should then be transferred into an individual cell.
Because CSV files are recognised by almost all spreadsheet programs, they are used as a simple way to export data or transfer it between different programs. However, CSV is a plain text format, so CSV files cannot include advanced spreadsheet functions like charts, formulas, filters, or formatting. There is also not currently a universal open standard for all CSV files.
XLS Document Format XLS Converter
The XLS file format was developed by Microsoft for its Excel spreadsheet program. XLS is a binary spreadsheet format that can include cell data and formulas, as well as charts and macros. Excel is one of the most popular software programs for recording, organising, calculating and analysing data. It’s often used for budgeting and reporting.
Microsoft introduced the new XLSX format for Excel in 2007, to replace XLS. However, you can still open XLS files in newer versions of Excel, as well as saving XLSX files into this older format. Excel is part of Microsoft’s Office suite, which is available as a one-off software purchase or an Office 365 subscription. Other spreadsheet programs that can usually open XLS files include Google Sheets, Apple Numbers and LibreOffice Calc.
