Claude can read and make sense of large documents, spreadsheets, and data sets, then summarize findings, answer questions, and create charts — acting like a research analyst who works at reading speed. Integrations with tools like Excel, Snowflake, and financial data platforms let businesses use Claude to query their data in plain English.

Claude's data analysis capabilities include document comprehension, spreadsheet analysis, chart interpretation, and data visualization through the Artifacts feature. A $200 million multi-year partnership with Snowflake, announced in December 2025, makes Claude available to more than 12,600 Snowflake customers for natural-language data querying, with the companies reporting over 90% accuracy on complex text-to-SQL tasks — meaning Claude can convert a plain-English question into a database query with high reliability. Integrations with financial data providers including S&P Global, LSEG, PitchBook, Moody's, and FactSet are available through Claude for Excel. The API includes a sandboxed code execution tool that allows Claude to write and run Python scripts for data analysis tasks.
