Hi Terry McCoy2,
Thanks for visiting Microsoft Community.
When using the 'Locked' and 'Hidden' features in Excel cell formatting, and enabling worksheet protection, it's clear that the formula in such cells cannot be applied to other cells. This ensures that the content you wish to protect cannot be obtained or inferred in any form.
Based on your needs, you can first disable worksheet protection, then after editing the formulas and other contents of the worksheet, re-enable protection before sharing it with others.
Please let me know your thoughts on this.
Best Regards,
