Export Function

This is a description of the export processing and execution sample.

Export Processing

  1. The application divides the data (command, export data, style) for export in certain sizes, and it sequentially transmits the divided data (chunked data) to the Nexacro-xeni server.

  2. The Nexacro-xeni server configures the transmitted data into the file stream to be saved according to the command.

  3. Create an arbitrary folder in the specified pathway and create the stream as a file with the specified name.

  4. The URL of the created file is transmitted to the application so that the file may be downloaded.

  5. Request the URL.

  6. The Excel file is transmitted.

  7. The created file is managed/deleted according to the settings.
