The application relates to a structured processing method of construction data table data. The method includes: carrying out basic-characteristic marking on unit grids; placing corresponding data value storage IDs in label information of filling-data-type unit grids; generating data description contents for filling-data-type unit grids; processing the unit grids of an entire construction data table to form a storage structure for the data description contents of the construction data table and the corresponding data value storage IDs; saving the generated storage structure, and forming a datadescription structure library; using a construction data table template library, of which structured description is already carried out, at a computer terminal for construction data compilation, and storing data values in the filling-data-type unit grids; and forming the data description structure library and a data content database on a cloud server to complete structured processing on the data of the engineering data table. According to the method, fully structured processing can be carried out on the construction data table, an automation processing rate is high, and data storage is convenient.
