XLSX (Microsoft Excel Open XML Spreadsheet) is best for business data analysis with formulas, pivot tables, charts, and conditional formatting. Key tradeoff: TSV's advantage is tab characters almost never appear in natural text, eliminating the csv quoting/escaping problems that occur with commas in data, while XLSX's advantage is full-featured spreadsheet with 1,048,576 rows, formulas, pivot tables, charts, macros (xlsm), and conditional formatting.
