Large-data-volume Excel file exporting method based on asynchronous processing

The invention relates to a data exporting method, particularly to a large-data-volume Excel file exporting method based on asynchronous processing. At present, an exporting method for processing massive data occupies overlarge memory resources. The method comprises the steps as follows: an Excel auxiliary application module divides Excel data into multiple data sets; when an application system sends an Excel data exporting request to the Excel auxiliary application module, the Excel auxiliary application module makes Excel data exporting requests to a plurality of processors; each processor builds a new Excel file in a designated storage path when processing the Excel data exporting request; and a plurality of Excel files are overlaid to form a complete Excel file, and a user checks and downloads the generated Excel file in the storage path. According to the technical scheme, the service processing time is short, occupied memory resources of single processors are small, the system performance cannot be affected, and the user use friendliness is improved.
