SSL certificate is the foremost important aspect of any website. If your website is running without the SSL, the modern browsers will stop the users from entering the website. Of course, there are ways to bypass that, at your own risk.

MS Excel currency converter - Number to words Latest version

MS Excel currency converter 3.0 has been updated with bug fixes. This is the new version of my amazing currency converter VBA utility for MS Excel.
