PS: You can download excel sheet by clicking on Hamburger Menu --> DownloadXLSX

This is my codeSandBox, What I have tried so far: https://codesandbox.io/s/export-stockchart-forked-6zx5qj?file=/src/index.js

I want to remove that "chart" label from the downloaded excel sheet. I have tried to set chart title to "undefined" and "null", But none of the method is working. Please suggest me some ideas. Thanks in Advance.

You need to disable the tableCaption option:

  exporting: {
    tableCaption: false,
    ...
  }
