Creating an .xlsx file is straightforward. Simply open Microsoft Excel or any compatible spreadsheet application, and you can start creating your spreadsheet. You can input data into cells, format the cells, and create formulas to perform calculations. Once you’ve finished creating your spreadsheet, you can save it as an .xlsx file by clicking the “File” menu, selecting “Save As,” and choosing the .xlsx format.

Opening an .xlsx file is equally simple. Most spreadsheet applications, including Microsoft Excel, Google Sheets, and Apple Numbers, support the .xlsx format.
