marshmallow sd card issue

[AC Question]

I have Lenovo a7000. I updated lollipop to marshmallow, then I have bought 32 GB SanDisk micro SD card and set as internal storage after some time I format the phone now SD card not open in any devices how can I open SD card and recover data?

It's no possible. When you choose the internal storage option, the phone generates an encryption key which is needed to decrypt storage. If you reset the device a new key gets generated and you lose access to the SD card.

I agree with Pugs1956. Once you set an SD card as adoptable storage it can't be used on a different device, no matter what you try.
