The invention discloses a generation method and a device of report data which are applied to a default report data summarization model. The generation method comprises the following steps: according to the report data summarization model, obtaining report design data and a report template corresponding to the report design data which are set by a user; according to the report design data, summarizing various data items in a source data table to generate a summarization table, wherein the summarization table comprises multiple index data tuples; in the summarization table, extracting target index data tuples corresponding to received keywords; writing each target index data tuple into the report template according to the keyword of each target index data tuple to obtain report data. According to the embodiment of the invention, in the implementation of the design and generation of the report data, a user only needs to set the report design data and the keywords of the report data which are actually required to be obtained according to the default report data summarization model, so that the accuracy and efficiency of the generation of the report data are improved.
