REGEX in Excel and Google Sheets to fix messy text

TEXTAFTER, LEFT etc. can clean text in Excel/Google Sheets but when we need more sophisticated stuff to for example extract any email address from a cell or keep the text only, or only the first word, these brand new functions can help.
Using regular expressions REGEXEXTRACT, REGEXREPLACE, REGEXMATCH/REGEXTEST can really help for complex scnearios.
