DeepTable vs Tableau

DeepTable is a cloud service that converts human-formatted Excel spreadsheets into clean, relational tables suitable for SQL workflows. Its LLM-powered engine interprets spreadsheet structure, relationships, merged cells, complex layouts, and visual formatting. The API accepts Excel .xlsx uploads up to 100MB and can return SQLite, Parquet, or CSV output. Every output value includes a reference to its source cell, allowing values to be traced back to the original sheet. Listed uses include RAG pipelines, AI agents processing business spreadsheets, SaaS spreadsheet ingestion, and enterprise internal tools. Developers can use TypeScript, Python, or Go libraries, or the command-line tool; API and Linux are listed platforms. The provider says uploaded spreadsheets and processing results are not used to train or fine-tune AI models. Users choose retention periods and may delete data, which is encrypted in transit and at rest. DeepTable is in private beta, with pricing on request.
