An information processing apparatus includes a first replacing unit, an obtaining unit, and a second replacing unit. The first replacing unit replaces, in first document data including plural character strings, a first character string which satisfies a predetermined condition by a second character string including a character string which is not included in the first document data so as to generate second document data. The obtaining unit obtains a processing result generated by processing the second document data. The second replacing unit replaces the second character string included in the processing result by a character string corresponding to the first character string.
