File To Database Skill — Data skill for Claude Code

🗄️ File to Database

   

**English** | **[中文](README.zh-CN.md)**

Turn raw data files (CSV / Excel / JSON / JSONL / TSV) into a validated database — then keep operating it in natural language: queries, inserts, updates, and deletes with safety gates, audit logs, and a visual delivery package after every change.

**7 reference docs** encode the full engineering loop. **6 file formats** supported. **0 dependencies** (stdlib Python only; openpyxl optional for xlsx).

**The problem:** "Send the files to Cursor and it builds a database" works once, but every new project means re-explaining your design rules, the agent guesses foreign keys and indexes differently each time, and after the DDL you're on your own. File to Database fixes all three: your design methodology lives in `references/methodology.md` (swap it to change the design style), every generated schema follows it verbatim, and the runtime mode keeps the agent as the database's natural-language operator afterwards.
