Encryption in Excel

Hi Elaine, thanks for your query. This is a tough one to advise one because of course the second we recommend something it will be decrypted, your data read and you'll be very annoyed with us! So a couple of things: a) nothing is bulletproof, but password protecting your data (Tools - Options - Security) satisfies most users within a company, b) if you are sending your data to different sites ask IT whether they use a VPN (Virtual Private Network) to do so and c) if you need to go further the most widespread data encryption tool is PGP (Pretty Good Privacy) which you can read about here:

Hope this helps,

Anthony
