  Hello.

  I’m trying to get SpreadJS to work with Node.js.

  I tested whether the attached sample code works with version 17.1.10.

  However, I encountered the following error:

  ReferenceError: HTMLElement is not defined

  The same error also occurred with version 17.1.5.

  It seems to work with version 17.0.10. Do you have any idea what might be causing this error?

  Hi,

  Please include the following lines in your sample:

  global.HTMLElement = window.HTMLElement;
  global.HTMLDivElement = window.HTMLDivElement;
  global.customElements = null;

  You can refer to the updated blog post on importing and exporting XLSX files using SpreadJS for more information: https://developer.mescius.com/blogs/how-to-import-export-excel-xlsx-using-node-js

  Additionally, please note that license information is confidential and should not be shared on public forums. As a result, I have removed the sample from this forum case.

  Attached is a modified sample that you can use in your application. Kindly ensure to set valid license keys for SpreadJS and ExcelIO before running the attached sample, as the provided sample does not include them.

  If your sample contains confidential data, I recommend creating a case on our private portal at: https://developer.mescius.com/my-account/my-support

  Further, ExcelIO is an old module used for import/export and the developers recommend using the new SJSIO module for import/export. Refer to the following demo on Import/Export that uses the new SJSIO Module: https://developer.mescius.com/spreadjs/demos/features/spreadjs-file-format/overview/purejs

  Feel free to reach out if you encounter any issues.

  Best regards,

  Ankit
