+            the same philosophy that Flectra implements overriding the main library
+            to avoid the 31 characters limit triming the strings before sending them
+            to the library.
+
+            In some cases, there's not much control over this as the reports send
+            automated data and the potential exception is hidden underneath making it
+            hard to debug the original issue. Even so, different names can become the
+            same one as their strings are trimmed to those 31 character limit.
+
+            This way, once we come across with a duplicated, we set that final 3
+            characters with a sequence that we evaluate on the fly. So for instance:
+
+            - 'Sheet name' will be 'Sheet name~01'
+            - The next 'Sheet name' will try to rename to 'Sheet name~01' as well and
+              then that will give us 'Sheet name~02'.
+            - And the next 'Sheet name' will try to rename to 'Sheet name~01' and then
+              to 'Sheet name~02' and finally it will be able to 'Sheet name~03'.
+            - An so on as many times as duplicated sheet names come to the workbook up
+              to 100 for each sheet name. We set such limit as we don't want to truncate
+              the strings too much and keeping in mind that this issue don't usually
+              ocurrs.
