Hey everyone, thanks for checking out MildlyTyped. I built this after repeatedly dealing with messy CSVs, brittle imports and “almost-structured” data in my work as a data engineer. Instead of magically fixing, MildlyTyped focuses on being pragmatic and predictable more like linting for data. You can use it to clean and normalize datasets, run validation rules, and generate TypeScript / Python models from real-world data. I’d love to hear how this fits (or doesn’t) into your workflow. Feedback, ideas and criticism are very welcome. Please note, your data is not saved anywhere! Also it is not loaded into any LLM. Thanks for taking a look
