Excel is definately faster because I can filter, sort, etc allowing me to work faster. There is one column, "shipping_params" which I may screw up by working in excel. Wonder if you can explain important variables in this "shipping_params" field especially the ones I cant omit. The string in this filed is of the sort,"O:8:"stdClass":14:{s:19:"shipping_percentage";s:1:"0";s:18:"shipping_min_price";s:0:"";s:18:"shipping_max_price";s:0:"";s:25:"shipping_virtual_included";s:1:"0";s:19:"shipping_min_weight";s:4:"3000";s:19:"shipping_max_weight";s:4:"3499";s:20:"shipping_weight_unit";s:1:"g";s:19:"shipping_zip_prefix";s:0:"";s:16:"shipping_min_zip";s:0:"";s:16:"shipping_max_zip";s:0:"";s:19:"shipping_zip_suffix";s:0:"";s:19:"shipping_min_volume";s:0:"";s:19:"shipping_max_volume";s:0:"";s:18:"shipping_size_unit";s:1:"m";}". It includes many variables which are self-explanatory including important ones like minimum and maximum weights. Which variable relates to shipping zone and where do I fish the values? Besides these three, min, max weight and shipping zone, is there any other important ones in this field/string?
