Is there any way to Migration Share Point 2010 to office 365 cloud with out using 3rd Party tool.
If you mean content, then there is no way to migrate except through a 3rd party tool.
If you mean 2010 solutions / custom code, then you will have to manually re-write to adhere to the new App model. Check out a similar answer:
SharePoint Online does not give the customer access to the Central Administration, and there are no Microsoft tools to help with migration from SharePoint Server 2010 to SharePoint Online.
So you have to be moved data manually or you may try third-party tools however this is unsupported by Microsoft.
