Computer file parsed these incorrectly (11)

I believe the answer is:
spreadsheet
'computer file' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'parsed these incorrectly' is the wordplay.
'incorrectly' indicates anagramming the letters (I've seen this in other clues).
'parsed'+'these'='parsedthese'
'parsedthese' with letters rearranged gives 'SPREADSHEET'.
Can you help me to learn more?
(Other definitions for spreadsheet that I've seen before include "Figure manipulating program" , "Table-creating software" , "Computer program allowing easy entry, tabulation and manipulation of figures" , "Computer program layout" , "Computer program allowing easy calculations for financial planning" .)
