Two points here:
1. Your transmission is corrupted !
2. Very many utilities enter in the course of more involved programs.
By over-killing native code, user over-kills his own project.

Jean,
1. Define corrupt? I just grabbed the existing code and put them into an if/else loop.
2. Feel free to copy and paste the individual code into the Nest2Matrix function and it becomes standalone

You need to stop obfuscating the situation. If this utility is not for you, ignore it. I have no idea what you are trying to show in your attachment.

It zapped my work sheet in view.
Since many collabs are more recent than me 6179, it never happened.
It may be the transmission or a corrupted work sheet. That happens
whereas Smath does not warn "critical error occured". The construction
may look being carried but when saving, it saves "root element missing"
i.e: not even blank sheet [0 kB],
Smart enough, Smath does not save corrupted document.
It may be as well, some gadget or web crash the Smath code.
Many collabs reported "root element missing", has never been elucidated.
No more questions/answers.

I can open it in 6179... corrupted while downloading?
