All you need to know about spreadsheet file formats

Spreadsheets are all about horizontal rows, vertical columns, and cells. Besides storing data, every piece of information saved in the spreadsheet can be analyzed using formulas and calculations. For example, you can store information about a certain employe in one company. Each column can contain data such as name, address, phone number, date of birth, favorite food, etc. In that way, you are using a spreadsheet as a database. However, the spreadsheet can show its full potential when it comes to storing and analyzing any kind of information that includes numbers. That's why they are mostly used in the financial and scientific sectors. The most common format is Microsoft Exel, known as XLSX, but that's not the only extension in use.
