  • Publication number: 20160117412
    Abstract: Machine logic (for example, software) that performs the following steps: (i) providing a parent table including a set of nested table(s) so that the parent table has N levels of nestedness, with N being an integer greater than one; and (ii) extracting a first nested table at the Nth level of nestedness where N is an integer equal to or greater than one, with a value of one representing the root table, and with greater values representing tables nested within the root table; and (iii) replacing the first nested table with equivalent narration text. Software is agnostic with respect to parent tables having different structural patterns, different file formats, and/or different cell layouts.
