Node application (c++) + xlsb file = bad format if open-save twice?

Aspose.Cells Product Family

Hi there,
I am working on a project in which I’m using the node wrapper over the c++ library. In our case we narrowed down an issue to this simple operation: open file, then save file. Do this twice in a row on the same file (overriding the existing one, not making a new copy) and the format inside will be corrupted in a way that cell borders appear dotted, definitely changed… see below in the images attached

I managed to make a super-small version of the issue by just doing this:

        // Load the XLSB file
        const workbook = new Workbook(filePath);
        
        // Save the workbook in XLSB format
        workbook.save(filePath, SaveFormat.Xlsb);
        
        // Open the workbook again
        const workbookAgain = new Workbook(filePath);
        
        // Save it again in XLSB format
        workbookAgain.save(filePath, SaveFormat.Xlsb);

and the resulting file (an xlsb format one! with xlsx this doesn’t happen) gets somehow corrupted

after open-close twice in a row:

Can anybody help me?
I’m using the lates version available (25.10.0)

Hi guys!
Thank you very much for that!
I upgraded my software to use the latest one, but when trying to use it in our fork of n8n, we found this error:
2025-11-13 08:17:59.762

Importing custom packages failed: Failed to load nodes and credentials: Error: Unsupported platform or architecture: /home/node/.n8n/custom/node_modules/.pnpm/aspose.cells.node.linux.x64@25.11.0/node_modules/aspose.cells.node.linux.x64/aspose.cells.nodejs.node: undefined symbol: _ZN6Aspose5Cells25AbstractCalculationEngine15SkipCalculationEv, version libAspose.Cells
…

Is there a breaking change or something I should run before?

Thank you so much!

Please check the file sizes of these two files for v25.11 on a Linux x64 machine: aspose.cells.nodejs.node and libAspose.Cells.so, which should be 27,568,576 and 98,329,392 bytes, respectively. I was able to reproduce the issue you mentioned using aspose.cells.nodejs.node (v25.11) with an older version of libAspose.Cells.so. Additionally, please perform a fresh installation and test of v25.11 on a Linux x64 machine to see if it works properly. Thank you.
