Converting to CSV gives you a key advantage: universal data interchange — every database, spreadsheet, programming language, and data tool can read and write csv. CSV is best for exchanging tabular data between databases, spreadsheets, and programming languages with maximum compatibility.

expand_more
XLSM (Microsoft Excel Macro-Enabled Workbook) is best for spreadsheets with vba macros for automated data processing, reporting, and custom functions. CSV (Comma-Separated Values) is best for exchanging tabular data between databases, spreadsheets, and programming languages with maximum compatibility. Key tradeoff: XLSM's advantage is embeds vba macro code directly in the workbook, enabling automation, custom functions, and interactive userforms, while CSV's advantage is universal data interchange — every database, spreadsheet, programming language, and data tool can read and write csv.
