This skill empowers Claude to act as a sophisticated spreadsheet engineer, capable of creating, editing, and analyzing .xlsx and .csv files with a focus on financial modeling standards and scientific accuracy. It goes beyond simple data export by implementing dynamic Excel formulas (avoiding hardcoded Python results), adhering to industry-standard color coding and number formatting, and utilizing a mandatory recalculation and error-checking workflow. Whether building complex financial projections, generating scientific data visualizations, or managing large-scale data processing pipelines with pandas and openpyxl, this skill ensures publication-quality, error-free spreadsheet outputs.
