Финансовые модели Excel по банковским стандартам

★ 7.1 · financial-analysis

excel-author is a Claude Code skill that builds auditable .xlsx financial workbooks in headless mode using Python openpyxl, following banker-grade conventions throughout. Every calculation cell must be a live Excel formula string — never a Python-computed value pasted as a number — with blue font marking hardcoded inputs, black for formulas, and green for cross-sheet links. The skill generates a Checks tab with TRUE/FALSE balance sheet and cash flow tie-outs, manages cross-sheet references via openpyxl DefinedName named ranges, and attaches source comments to every hardcoded input cell at creation time. Sensitivity tables are built with an odd number of rows and columns so the center cell always represents the base case. Designed for analysts building DCF, LBO, 3-statement, or any financial model that needs to be reviewed and flexed by someone other than its author.
