The SPARTA JSON Creator is a tool for creating JSON objects to be used in the various SPARTA mapping tools; Navigator, CM Mapper, and Control Mapper. The user can easily copy/paste SPARTA TTPs, SPARTA Countermeasures, NIST 800-53 Rev 5 IDs, or ISO 27001 IDs into the top text area and convert the data into a specific SPARTA tool format. This JSON can then be downloaded and imported into the tool for editing and creating visuals. The expected format of the controls MUST match the format within the Countermeasure section of SPARTA (NIST, ISO) . For example, NIST control must match control family-control number(ehancement number) with no leading zeros. This would look like AC-2(1) and not AC-02(1) or AC-02(01).
