To solve the issue of exporting empty Excel data, you can troubleshoot and address it by following these steps:<\/p>\n

    \n
  1. Check the data source: verify if there is data in the data source. This can be confirmed by printing or debugging the relevant code of the data source to see if data has been correctly loaded.<\/li>\n
  2. Verify data export logic: Ensure that the logic for exporting data is correct. Check the relevant data processing code to ensure that data is properly retrieved, processed, and exported to Excel.<\/li>\n
  3. Check the Excel template: If you are exporting data based on an existing Excel template, make sure the template file is correct and valid. You can try opening the template file to check if the data and formatting are as expected.<\/li>\n
  4. Check the export file path and name: Verify that the saved path and name of the exported Excel file are correct. Try changing the save path and name, then run the program again to export and see if it generates the correct Excel file.<\/li>\n
  5. Check the version of the dependency library to ensure the correct version of the POI library (such as Apache POI) is being used. Different versions of POI may have different ways of using the API, which could lead to unsuccessful data export. You can try updating the version of the POI library, or refer to documentation and example code to ensure proper use of the POI library for exporting data.<\/li>\n
  6. Exception handling: Capture and handle any potential exceptions that may occur during the data export process. This can be done by printing out the exception information or using debugging tools to identify and resolve the issue.<\/li>\n<\/ol>\n

    If the above steps do not solve the issue, you can provide more detailed code and error information to better help you resolve the issue.<\/p>\n","protected":false},"excerpt":{"rendered":"
