Работа с Excel-файлами и таблицами

automation

xlsx is a Claude Code skill that creates, edits, and analyzes spreadsheet files — including .xlsx, .xlsm, .csv, and .tsv — directly within a Claude session. It uses pandas for data reading and analysis, openpyxl for formula and formatting work, and recalculates formulas via LibreOffice and a recalc.py script to ensure zero formula errors (#REF!, #DIV/0!, #VALUE!, #N/A, #NAME?). Financial models follow industry-standard color conventions: blue for hardcoded inputs, black for formulas, green for intra-workbook links, and red for external file references. The skill is designed for financial modeling, report automation, data cleaning, and building dynamic spreadsheets that recalculate automatically when source data changes.
