This method uses a plug-in: jacob-1.15-M4. This plug-in can convert office to html. I only introduce one here, converting Exl to html. Some of the converted html The border line is 0.5px. Some browsers do not recognize the 0.5px border line. You need to convert the 0.5px in the generated CSS to 1px. If you need to convert multiple times in the system, it is recommended to write a singleton mode. Otherwise, your computer's memory will be exhausted after several conversions. The reason is very simple, that is, each conversion will start the Exl program. If it is started too many times, the system memory will be full. Therefore, it is recommended to write in singleton mode. Without further ado, just post the code:
