Both formats, briefly
XLSXIN
XLSX is the workbook format Excel writes today, built on Open XML. A single file can hold many sheets along with formulas, charts, pivot tables and conditional formatting rules. Choose it when the calculations need to travel with the numbers instead of only the results.
CSVOUT
CSV stores a table as lines of text with commas between the values. There is no styling and no formulas, just rows and columns, which is exactly why databases, analytics tools and every spreadsheet program accept it. Use it to move data between systems that share nothing else.
