I don't know if it's an issue, but tests don't check for items with more then two words for an expense name
the line like 131 Fresh flowers 12.2 will break some solutions.
If the fixed number of whitespaces is intended - ok, but it will add a little additional challenge to the kata

Oooh, I didn't know you can use bool as an int depending on placement.
I wrote header = 1 in my own solution, but you can just use "header", like you did, and it will convert to either 0 or 1 .
Thanks!
