There are a few ways to make an Excel spreadsheet. One way is to open up a new spreadsheet by clicking on the "New" button on the top left corner of the Excel window. You can also open an existing spreadsheet by clicking on the file name on the left side of the Excel window. Once you have a spreadsheet open, you can start entering data into the cells. To enter data, click in the cell you want to enter data in and start typing. You can also enter data by selecting the cells you want to enter data in and then clicking on the "Enter" button on the keyboard. You can also copy and paste data into Excel spreadsheets. To copy and paste data, select the cells you want to copy and then click on the "Copy" button on the toolbar or press "Ctrl+C" on the keyboard. Then go to the cell where you want to paste the data and click on the "Paste" button on the toolbar or press "Ctrl+V" on the keyboard.
