is there any tool available on the internet from where i can check that my site is affected by goolge sandbox
As far as I know there is no tool for finding sandbox. In fact, nobody knows for sure whether sandbox exists or not.
serach your domain in google if it is rank on 1st page then there is no worry if it will be rank on page 5 or 6 then there is some penalty, for the example: spouse it's your site domain.com if you are search domain.com then it will placed on first page ether there is penalty or not so you should be search only domain don't use extension then you will find the exact result. and according to me this is the only tool or method which we can use.
ya even iam agree there is no tool but check your domain if it is find first then it is ok otherwise u have to wait for sometime cheers
