Excel

Hi Kerry,
Thanks for your post, welcome to the forum, in answer to your question there are two ways to set a Workbook password;
1. Go to Menu command File>Save As and in the Save In dialog box, click the Tools tab, from the menu choose General Options and then insert your chosen password, Confirm the password, Click Ok, Name and Save your Workbook. When you next open you will be prompted for a password.
2. Whilst in the Workbook, select the Menu command Tools>Options and in the Security Tab enter Password and Confirmation. As above you will be prompted before you can open the workbook.
Remember not to lose the password, if you do you will not be able to open the Workbook (Ever). I hope that has been of use to you, if so please click the resolved link, regards Pete.
