Use MainBook to convert statement PDFs and report what its arithmetic validation and row-level flags actually show. A passed check means the extracted statement math reconciles; it does not prove that every field was extracted correctly.
Mainbook Bank Statement Converter is a community-contributed Claude Code skill in the conversion sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/mainbook-bank-statement-converter/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when a user wants PDF bank or credit-card statements converted through the MainBook MCP tools to XLSX, CSV, or JSON, or wants an existing conversion checked for arithmetic mismatches and warning rows. Covers page-credit preflight, timeouts, local versus hosted file handling, and multi-statement workflows.
