The matrix is a unique file, meaning that the probability of creating two identical ones is practically nonexistent.
During its creation, two versions of the same matrix are generated:

A .xlsx version, which can be viewed with any spreadsheet software (OnlyOffice, LibreOffice Calc, Excel, etc.).
A .json version, essential for encoding and decoding through the app.

The .xlsx version allows manual text encoding and code decoding without using the app.
It can also be useful for manual verification, though this process will obviously take much longer.

The matrix consists of three main parts, which we will call Zone A, Zone B, and Zone C.

We mentioned the possibility of performing manual checks, and the image below of the .xlsx matrix allows us to do so immediately, in line with this tutorial.
Let's start by visualizing these three zones.

Here is the list of characters that can be encoded with Cyphersol.
In total, there are 215 characters, including uppercase, lowercase, accented letters, numbers, symbols, special characters, space, and newline.
(*) As for encoding space, the reference on the matrix will be the Chinese ideogram 愛, present in row 2, while the newline operation can be identified by the Chinese ideogram 穴, present in row 3.
