As @FrankPl mentioned, there is no way to convert from SSAS multidimensional to SSAS tabular. If that is truly a requirement, then the best approach is to build the Tabular from scratch based on the same source used by the existing SSAS multidimensional.

@FrankPl : I want use SharePoint Power Pivot and I think that in situation I have to use SSAS in tabular mode. Now I have 8 Multidimensional Database and more that 30 Cube in Dimensional Mode. Should I convert my Multidimensional Database to Tabular mode? – loup

PowerPivot with SharePoint uses a "special" type of SSAS tabular instance (see this link). The only way to deploy models to the PowerPivot SSAS instance is to upload PowerPivot workbooks to SharePoint. SharePoint then extracts the PowerPivot model from the Excel workbook and publishes it to the PowerPivot SSAS instance. You should not deploy a SSAS tabular model created in SSDT/VisualStudio to this PowerPivot SSAS instance (truth be told, I'm not actually sure if the software prevents this)...because this instance is optimized for many small tabular models (as opposed to a few larger tabular models).

Furthermore, if you're only requirement is to use SharePoint + PowerView and your SSAS Multidimensional instance/server is at least version 2012 SP1 Cumulative Update 4, then you don't need to worry about converting to SSAS tabular. See this link for details.
