    Introduction

    This section outlines possible reasons why some Office documents may be rendered differently than expected.

    MS Office Documents do not Render in the Viewer using MSO Rendering Mode

    Below are some reasons for intermittent or continuous issues when viewing MS Office documents.

    1. Check the environment (CPU/RAM) to ensure it is properly sized according to the PrizmDoc Server Sizing recommendations. If you do not meet the sizing requirements, increase your system resources to match sizing recommendations.
    2. Check the NonInteractiveSystemHeapSize value using the table in the Registry Changes section. If it is not correct, set the registry key to match the table and restart your server.
    3. Verify whether your MS Office version is up to date. You can find the latest available updates for your version by checking: Update history for Office 2013 or Update history for Office 2016 C2R. If you are not on the latest version, upgrade to the latest patch for your version and restart the server.

    Office Documents Render Differently in PrizmDoc than MS Office

    PrizmDoc has two different rendering engines: LibreOffice (LO mode) and MS Office (MSO mode).

    In LO rendering mode, it is expected that there will be some differences from MS Office. To make sure the PrizmDoc is operating in MSO rendering mode, check whether your PrizmDoc Viewer license includes MSO support and whether the steps described in Natively Render MSO Documents are followed.

    Alternatively, check how the document is rendered in MS Office Print Preview mode, and compare it with PrizmDoc output.

    For Excel documents, please note that PrizmDoc has its own pagination mechanism enabled by default. For details, refer to the Central Configuration topic.

    If you prefer the MSO rendering and are not currently licensed, please speak with your sales representative for information regarding this feature.

    Excel Documents Render in PrizmDoc with a lot of Pages Compared to MS Excel

    When comparing PrizmDoc Viewer output to MS Excel output, consider that MS Excel shows the document content in "Normal View" mode by default, which does not split the content into pages. Your document might have special formatting or small text in a cell that is not visible on the screen.

    To see how many pages are actually there, switch to Page Layout View mode or go to Print Preview -> Print Entire Workbook and see how many pages there are, and what the document will look like when printed. Once you've located the cell with the unexpected data, you can delete it, and then it will render the same.

    Office Documents Render Asian Characters Incorrectly

    When opening Office documents with Asian characters in PrizmDoc Viewer, the document may contain unrecognizable characters.

    This can occur when the specific font type in the document is not available on the PrizmDoc Server. The PrizmDoc Server will attempt to use the most suitable font available which can produce less accurate results.

    In order to assign a proper match of fonts, refer to the following topic for more information: Substitute Fonts for Office Rendering Fidelity
