How to learn natural language processing

Learning NLP and using a natural-language data tool are different goals. For CSV analysis, you can start with a clear question and validate its SQL without building a language model.

A practical learning path

If you want to build systems, start with Python text handling, tokenization and a simple classification task. Split your examples into training and held-out evaluation sets. Examine incorrect predictions before moving to embeddings and language models. Keep personal information out of practice datasets.

For text-to-SQL, add database fundamentals: column types, joins, grouping and null handling. Build an evaluation set of questions with known answers and test both syntax and meaning. A query that executes successfully may still answer the wrong question.

If your goal is answering spreadsheet questions today, use the CSV-to-SQL walkthrough. QueryAI is an analysis tool, not an NLP training course.
