Parameters

| value | scalar | ✔️ | The value to convert to guid. |
Returns
The conversion process takes the first 32 characters of the input, ignoring properly located hyphens, validates that the characters are between 0-9 or a-f, and then converts the string into a guid scalar. The rest of the string is ignored.
If the conversion is successful, the result will be a guid scalar. Otherwise, the result will be null.
