Add custom properties to ".xlsb" files using openxml sdk in RRS feed

  • Question

  • Hi,

    I am creating an application which adds custom properties in office documents.

    I am using open xml sdk dll for adding custom properties for xlsm, xlsx files.

    I am using (..)  for adding custom properties.

    But i am not able to add custom properties in .XLSB files using (..)

    Is there any other way of adding custom properties from .xlsb

    XLSM and XLSX are working fine using (..)

    Please help and suggest how can i add custom properties in .XLSB files using openxml sdk package dlls.

    or any other class would be fine.

    I also have tried using dsofile dll. But on servers it is giving issues with office 2007 and above formats.

  • Hi,

    .xlsb means this is an Excel Binary Workbook, we can’t use OpenXML SDK to open it since it is not a file with open xml file formats.

    We can use Office PIA to convert this .xlsb file to .xlsm or, xlsx, but it need to install Office on the server and Microsoft doesn’t recommend us to use Office PIA on the server. For more information, please refer to Considerations for server-side Automation of Office.

    Suppose this xlsb file was uploaded from web, I would suggest you converting this file (Save as feature) to open xml file formats (e.g. .xlsm, .xlsx files) manually before uploading.

    In addition, to add custom properties, here is an article for your reference:

    Hope this helps.
