Best Load Planning Software for Google Sheets

ContainerMath is a 3D load-planning platform that turns messy cargo lists into optimized, balanced, and exportable packing plans for cartons, crates, shipping containers, trailers, and rail wagons. Users can paste a dispatch list, packing list, or Excel data, and its AI manifest import reads quantities, dimensions, and weights, normalizes units, and structures the cargo for planning. Carton Fit determines how many products fit into a shipper carton or crate and calculates units per box, boxes required, and optional weight limits. Freight then arranges mixed cargo into high-density 3D load plans using actual geometry, orientation, stacking rules, and pipe nesting where needed. Interactive 3D views and readable 2D cross-sections show placement order for loading crews, while center-of-gravity, payload, weight-distribution, and axle-balance analysis help prevent unstable or overloaded shipments.
