Method and quality
CSV keeps a table of values, not formatting, charts or multiple sheets. Numbers are read as decimal text, dates become ISO 8601 and formulas use saved results only.
Practical example
A workbook with Sales and Customers exports the selected sheet. Quoted fields preserve commas or newlines inside text.
Formats and limits
XLSX up to 128 MB, 100 sheets, 100,000 rows, 1000 columns and 1,000,000 cell positions across the workbook. Formulas are not recalculated. CSV protection prefixes potentially executable formula text with an apostrophe.
