Excel and CSV explained
What is a Excel file?
XLSX is the modern Microsoft Excel spreadsheet format. It stores cells, formulas, multiple sheets and formatting, and is the standard for working with tabular data.
What is a CSV file?
CSV (Comma Separated Values) is a simple text format for tabular data. Almost every spreadsheet and database can read and write CSV, which makes it the lingua franca of data exchange.
