How to Megre XLSM to JPEG in Cloud Apps

  1. Initialize WordsApi with Client Id, Client Secret, Base URL & API version
  2. Set requestDocument assign the local XLSM file name
  3. Set requestDocumentListDocumentEntriesFileReference and assign local JPEG file name
  4. Set requestDocumentListDocumentEntries and set file_reference, import_format_mode parameters
  5. Create DocumentEntryList instance and assing requestDocumentListDocumentEntries to document_entries parameter
  6. Call AppendDocumentOnlineRequest to merge XLSM file with JPEG document requestDocument and requestDocumentList
  7. Call WordsApi appendDocumentOnline with parameters

Get Started with Aspose.Total REST APIs

  1. Create an account at Dashboard to get free API quota & authorization details
  2. Get Aspose.Words and Aspose.Cells Cloud SDKs for C++ source code from Aspose.Words GitHub and Aspose.Cells GitHub repos to compile/use the SDK yourself or head to the Releases for alternative download options.
  3. Also have a look at Swagger-based API Reference for Aspose.Words and Aspose.Cells to know more about the REST API.

FAQ

  • What is XLSM Format?
    Files with XLSM extension is a type of Spreadsheet files that support Macros. From application point of view, a Macro is set of instructions that are used for automating processes. A macro is used to record the steps that are performed repeatedly and facilitates performing the actions by running the macro again. Macros are programmed with Microsoft&rsquo;s Visual Basic for Applications (VBA) from within the Excel Workbook using the Visual Basic Editor and can be run/debug directly from there.
  • What is JPEG Format?
    A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image. The higher the compression value, the higher the degradation in image quality.
