What is an Excel File?
Excel files (.xlsx and .xls) are spreadsheet documents created by Microsoft Excel, the world's most widely used spreadsheet application. The modern XLSX format, introduced with Office 2007, uses Open XML — an open standard based on XML and ZIP compression that makes files smaller and more reliable than the legacy binary XLS format.
Excel spreadsheets are the backbone of business data management worldwide. From financial modeling and budgeting to inventory tracking and project planning, Excel files are used by an estimated 750 million people globally. The format supports multiple worksheets, complex formulas, charts, pivot tables, and conditional formatting.
While Microsoft Excel is the most popular application for creating and editing these files, the XLSX format is supported by Google Sheets, LibreOffice Calc, Apple Numbers, and many other spreadsheet applications. Our online viewer lets you open and inspect any Excel file without installing software.
