Show HN: DataFlowMapper – Data transformation for messy data without coding (dataflowmapper.com)

I built DataFlowMapper to solve my own frustrations with data transformations during client implementations.

What it does: - Provides a visual interface to transform messy data (CSV/Excel/JSON) - Runs Python transformations row-by-row without writing loops - Includes a visual logic builder that generates Python code - Saves transformations as reusable mapping files - Built on Pandas with parallel processing for large datasets

The core problem I'm solving is the repetitive nature of writing similar transformation scripts for different data sources. Instead of starting from scratch each time, you can build transformations visually or with AI assistance, then save and reuse them. Also allows non technical users to build robust transformations without a steep learning curve

I'd love feedback from the HN community, especially from those who work with data transformations regularly. I'm offering extended lifetime access for anyone interested in trying it out.
