The convert menu may be confusing and dangerous without first becoming familiar with its purposes, and how each item works. Therefore, I’m writing up this help file to help you understand, but if you can read Python, I strongly recommend just looking at what the source code does, for the present. If you don’t know Python, or if you don’t want to interpret the source code, contact the developer for an explanation of the functionality. The item that begs explanation most is probably ‘Numbers to password text’. This allows you to select numbers written out in your text editor and enter a password. The password text is used to create a new counting system, and the numbers are converted to this new system.

The first set of menu items pertains to counting systems, such as Roman numerals, and the system used to count columns in most spreadsheet software. Some of these items also pertain to creating your own counting systems and to using custom counting systems to encode or decode text.

Although you may have other purposes for some of them, the second and third sets of menu items are used for formatting plaintext e-books (such as the .txt files you might find at Project Gutenberg) in certain ways, including as HTML.
