Answer :
To preserve the original workbook, use the Save As function to make and save a copy under a new name or at a different location, enabling you to work on the copy without affecting the original.
To preserve the original version of a workbook while allowing changes to be made to a copy, the best approach would be to save a backup copy of the workbook. This can be achieved by using the Save As function in your spreadsheet software. Here are the steps you might take:
- Go to menu item: File > Save As....
- In the Save As box, enter a file name for your document to differentiate it from the original version.
- In the Where drop-down menu, select the location where you would like to save this backup copy.
- Optionally, in the Format drop-down list, select a desired file format such as Excel 97 - 2004 Workbook (.xls) if needed.
- Click Select Save to complete the process.
Once the backup copy is saved under a new name or at a different location, you can freely make changes to the workbook without worrying about altering the original file.
