Hi,
Upon investigation, we found that the problem is with the Excel file. The file might have stored the state of row outline group as collapsed and therefore SpreadJS is showing +(Expand Sign) instead of -(Collapsed Sign).
We would like to know how you generated the Excel file. If the excel file is generated using any of our products, we would like you to mention the steps that you have followed, so that we can investigate the issue further at our end. There is a simple fix available to this issue.
Things we did to fix the issue:
Open the file in Excel.
Save the file without making any other changes.
Load the file in SpreadJS and it seems to be working fine. Upon saving the file in Excel, it saves the correct state of the collapsed row outline group.
Regards.
