MATLAB has a number of functions to perform various types of data preprocessing tasks. That page lists some of the functions for detecting and cleaning missing data, detecting and removing outliers, and normalizing data (which are the three tasks you described in your question) as well as data grouping / binning and data smoothing / detrending.

There are lots of tools available through the link.
We cannot tell you if there is a tool that can specifically help you because you haven't given us any details on what you're trying to do. All you've done is given us a general idea like, 'I want to build a house. What tools should I use?' The type of tools you need are highly dependant on what you are using to build the house. If you are using screws to build the house, then me giving you a hammer isn't going to help you very much. Because you haven't given us any details we've done the best we can, showing you where the tool box is, but we can't do any more until you give us more details on the specifics of what you're trying to accomplish.

If by "tool" you mean a GUI or an app, the answer is partially yes. In the just-released release R2019b, we introduced Live Editor Tasks. Two of the Live Editor tasks we introduced deal with cleaning missing data and cleaning outliers.
