    I have a large data set, SpreadJS will crash when trying to copy whole content.
    Step to produce:
    1. import the example csv file.
    2. Select All text (click top left corner)
    3. Ctrl + C copy, wait for copy indicator to show up.
    4. Ctrl + C again, the app will crash

    Please let me know any chances we could've implement optimization on coping and paste action, so that it will not crash.

    Hi Zhoubing,

    I think this is a limitation because of the number of cells being copied are large. I have also forwarded this to the dev team for further investigation and if any optimization is possible. The internal tracking id is: SJS-14006. I will let you know when I have an update for you.

    Meanwhile, could you please share your use case as to why you want to copy such large range so that we can have a better understanding of your use case and could assist you accordingly?

    Hi Zhoubing,

    The devs have informed that if you don't care about the style, using allowCopyPasteExcelStyle = false may enhance the performance.

    In the designer, you can use

    Also, if you are copying an entire sheet, it is better to just export to Excel or CSV instead.
