# Independent answer check

Type Clean note in C1 and =SUBSTITUTE(B2,CHAR(10)," ") in C2, then fill to C4. C2 should be Check box before packing; C3 Call customer by Friday; C4 Ready for pickup. B2:B4 remain unchanged. Exactly two embedded LF characters were replaced across the three notes.

Independent Python text replacement of U+000A with one U+0020 yields the three exact phrases above. Replacing with an empty string would yield boxbefore and Callcustomer, which fail.
