I’m building a data validation and cleaning tool. Users upload a dataset.csv and validation_rules.csv. I tried using LLMs, but hit rate limits due to large data and free plan limits. Now I’m exploring Pandera for static validation in Python

Reasoning Complete! šŸ¤– šŸ” Searched knowledge base: To help you use Pandera for validating your datasets with user-supplied rules, I'll look up the best ways to implement this in Python, including how to handle large files and dynamic validation rules. • Searching over 10 data sources from the following: File, Github File, Github Issue, Web • Found 57 documents that could be relevant from the following data sources: Github File, Github Issue, Github Pull Request. • Filtered down to the top 30 most relevant documents. • To help you automate the process of turning your validation_rules.csv into a Pandera schema, I'll look for best practices or examples on how to map CSV-based rules into Pandera's validation system. • Searching over 10 data sources from the following: File, Github File, Github Issue, Web • Found 54 documents that could be relevant from the following data sources: Github File, Github Issue, Github Pull Request. • Filtered down to the top 30 most relevant documents. • To give you the most practical advice, I'll look for examples or best practices on how others have built tools to convert a CSV of validation rules into Pandera schemas, so you can automate this step efficiently. • Searching over 10 data sources from the following: File, Github File, Github Issue, Web • Found 55 documents that could be relevant from the following data sources: Github File, Github Issue, Github Pull Request. • Filtered down to the top 30 most relevant documents. āœļø Generated answer: I now have enough information to give you a clear answer on how to use Pandera for your use case, including how to handle user-uploaded validation rules and what to expect regarding data cleaning.
It seems likely that Pandera is a strong fit for your use case. Pandera allows you to define data validation schemas in Python, supporting checks on column types, value ranges, nullability, and custom logic, all without LLMs or external API calls. You can define schemas programmatically or with class-based models, and validate large CSVs efficiently using pandas or other supported backends. Informative error reports are generated for any validation failures, and you can also preprocess or coerce data types as needed before validation. See the Pandera README and DataFrameSchema docs for examples. Would you like more detail on how to map your validation_rules.csv to Pandera schemas, or on integrating Pandera into your tool?
