VFP Code Converter - The economical code conversion tool for FoxPro, supports the conversion of legacy PRG code to 50+ modern programming languages using the latest machine learning models.

VFP Code Converter is optimized for making it quick and easy to import and convert all of your PRG files into a wide range of modern development languages. For many smaller projects, it is straightforward to re-develop forms/reports manually. By focusing only on the PRG files, VFP Code Converter is easier to use and more economical.

VFP Code Converter enables developers to instantly import and manage the automated conversion of hundreds of PRG files within an entire VFP project in a single window. Individual procedure/functions can be selected by name for single-click submission to the selected AI machine learning model. Output files are saved automatically as the results are received into a folder of converted scripts. Completed scripts are checked-off and the conversion progress is displayed above the grid of scripts. Completed scripts can be further processed by GitHub Copilot X and Visual Studio IntelliCode to complete the integration into the new project. VFP Code Converter supports conversions into the top 50+ most popular programming languages as found in the TIOBE index. Machine learning prompts are generated automatically, but the prompt text and source code fields are fully editable.

A wide range of AI models are available for selection during the conversion process. Updated models can be retrieved from the AI vendor via the Refresh Models button. This flexibility enables developers to choose the best model for their specific code conversion project. For instance, the text-davinci models generally work best when converting FoxPro 2.6 code to Visual FoxPro code with the generation of form creation code.

As a tool for code understanding, VFP Code Converter aids developers in understanding the original Visual FoxPro business logic in a conversion project to any of the supported programming languages. Currently available large language models have in-depth understanding of the underlying programming code. This means that the automated AI-based code conversion has the potential to perform excellent business logic conversion from one programming language to another.

VFP Code Converter should be thought of as a very economical first step in the journey to convert and understand the source code in the original FoxPro project. In fact, code understanding is one of the key reasons for using VFP Code Converter to start your project. The development process works best when the developer of a modern programming language is converting from a legacy language. As a subject matter expert in the modern language, the developer will appreciate the time savings of automating the conversion process. And more importantly, the developer will be able to immediately observe the generated output code and improve the conversion results. Typically an 85% - 95% conversion rate can be achieved with the automated conversion process, with GPT-4 models reaching the higher end (available with the Unlimited Edition license).

The PRG file import process is as simple as clicking the Open... button and selecting a FoxPro project folder. The FoxPro top-level folder and all of its enclosed folders are instantly searched for .PRG files, the scripts are written into the MigrationProcess.db3 SQLite database file. At the same time, a ScriptsStatus.JSON file is created for the purpose of storing the contents displayed in the grid, including the completion status. As scripts are processed, they can be checked off by the developer, providing an updated completion count above the grid.
