Maybe a stupid question, but you have one word in your input file, and it appears as 3 words with a pipe as the delimiter. ... how come?

You may use
sed 's/[ t]*|[ t]*/|/g;s/^[ t]*|[ t]*$//g' Input_File
There are two regexps here:
s/[ t]*|[ t]*/|/greplaces all|enclosed with optional whitespaces with a single|(the|in the regex matches a literal|char as per BRE POSIX standard)
s/^[ t]*|[ t]*$//gremoves all whitespaces at the start and end of lines. Note that|here is an OR operator (escaped because the BRE POSIX syntax is used).
See the online demo.
