Click on âFileâ and select âSave Asâ after youâve entered all data into the spreadsheet. Select âCSVâ under the âSave as typeâ dropdown menu. Type a name for your CSV file, then select âSave.â You have now created a CSV file, and commas will automatically be added to the file to separate each field.
Browse for the CSV file and open it as usual by double-click. If you are opening a .csv file, Excel will open it straight away and display the data in a new workbook. If you have selected a text file (.txt), Excel will start the Import Text Wizard. See Importing CSV to Excel for full details. Note.
