We suggest you to have a look at the release notes to get the complete list of features, enhancements and other fixes which are part of this new release. Let’s not wait another moment to review the release notes.  To get essence of the public release (Aspose.Cells for .NET v19.9), I am giving you preview of the new features and other enhancements available in it.

Adjust workbook compression level

The compression level of the workbook is an important factor while working with larger workbooks. You should have control over setting the priority to create either small file with little more time or create files quickly but having comparatively large file size. Aspose.Cells have now provided this control such that the developer will have the control to adjust the compression level. A new enumerator OoxmlCompressionType is provided which can be used to set the compression level. Following members are available under this enumerator.

  • Level1: The fastest but least effective compression.
  • Level2: A little slower, but better, than level 1.
  • Level3: A little slower, but better, than level 2.
  • Level4: A little slower, but better, than level 3.
  • Level5: A little slower than level 4, but with better compression.
  • Level6: A good balance of speed and compression efficiency.
  • Level7: Pretty good compression!
  • Level8: Better compression than Level7!
  • Level9: The "best" compression, where best means greatest reduction in the size of the input data stream. This is also the slowest compression.

Following example can be used to exercise this new exciting feature by changing the compression type and comparing the file size with the time taken to create this file.
