Somehow historically it happened that the address book in the organization was kept in an Excel file lying on the share. But there is a wonderful Active Directory in which all the data is there! I saved the employee from the heavy burden of bringing everyone into the file and made a knee-pad script in a couple of minutes. Well, the template, in another couple of tens of minutes bungled. We just run the script and we have html, which can be put anywhere, and politicians add it to the bookmarks of all employees.
