The invention relates to an intelligent verification algorithm, an intelligent verification method and an intelligent verification device for a report designer. The method comprises the following steps of: verifying according to a data source, function parameters, a calculation and display expression, a statistical chart expression, cell cross-reference dependence and the like configured in a report designer template rule, after completing configuration of one item for the report designer automatically triggering verification whether the specifications or requirements of a verification algorithm are met or not, i.e., automatically verifying a design expression or other functions and the like after the design expression or a function is completed, so that the conditions that sending all verification requests to a background for verifying one by one during click storage after the design of an entire report sheet is completed, and causing unnecessary background service pressure are eliminated, and the rapidness and friendliness of report design verification are realized. Verification comprises data source verification, expression verification, function parameter verification, cell verification and the like.
