As per the Companies Act 2013 & Companies Incorporation Rules 2014 there is no specific provision for this type of conversion. As Sole Proprietorship Firms are not governed by any law. It is difficult to find any straight way to convert it.
A Sole Proprietorship Firm is an ordinary type of doing business. It is not registered under any law, but still, people use to register it. Because it has almost no compliance as compared to the private limited company and other form of corporate business.
The reason to incorporate Private Limited Company is to grow your business and save the goodwill of the business.
A private limited company is registered under Companies Act 2013; The company is registered under the jurisdiction of the central government. Which gives the immunity to the company thier name from all over India.

If somebody does, then company Director can file a suit against them.
