How to Parse API Response.

Does anyone know a decent way to parse a response that look like this.  Ultimately I'm going to drop it in a database but  could work with it in an array.  there will be multiple groups and subgroups involved.   Any help is greatly appreciated.

[{"name":"AIR CONDITIONER & HEATER","key":"108","htaccess":"air-conditioner---heater-108","groups":
    [{"name":"Condenser, compressor & lines","key":"30128","htaccess":"condenser--compressor---lines-30128","subgroups":
       [{"name":"Check valve ","htaccess":"check-valve--47177","key":"47177"}
        ,{"name":"Clutch","htaccess":"clutch-31529","key":"31529"}
        ,{"name":"Clutch coil ","htaccess":"clutch-coil--46412","key":"46412"}
        ,{"name":"Compressor assy","htaccess":"compressor-assy-31060","key":"31060"}
        ]
      }
     ]
  }
]
