1. Open Microsoft Excel and ensure that you have multiple workbooks or worksheets that you want to arrange on your screen.
2. Click on the “View” tab located in the Excel ribbon at the top of the window.
3. In the “Window” group of options, you will find the “Arrange All” button. Click on it.
4. A dialog box will appear with several arrangement options. You can choose from the following:
   • “Tiled”: This option arranges the open windows in a grid pattern, ensuring that each workbook or worksheet is visible and shares an equal amount of space on your screen.
   • “Horizontal”: This option arranges the open windows side by side in a horizontal manner. Each workbook or worksheet will be stacked horizontally, allowing you to easily compare data between them.
   • “Vertical”: Similar to the “Horizontal” option, this choice arranges the open windows vertically. Each workbook or worksheet will be stacked vertically for convenient data comparison.
   • “Cascade”: This option cascades the open windows, with each workbook or worksheet appearing slightly offset from the others. The title bars of the windows will be visible, allowing you to easily switch between them.
5. Select the desired arrangement option by clicking on it, and then click the “OK” button.

Excel will then rearrange the open workbooks or worksheets on your screen based on your chosen option. You can resize, maximize, or minimize each window as needed. This feature helps you multitask and work efficiently with multiple datasets simultaneously.

Remember, the “Arrange All” option in Excel is designed to enhance your productivity by providing a clear view of multiple workbooks or worksheets. It enables you to compare, analyze, and perform operations across different files with ease.
