What is a CSV file?

The CSV (Comma-Separated Values) file format is a plain-text format used for storing tabular data in a structured manner. Each line of the file represents a row of the table, and values within each row are separated by commas or other delimiters. CSV is widely employed for its simplicity and compatibility with various applications, facilitating the smooth exchange of data between different systems. It is a popular choice for data storage, data transfer, and spreadsheet applications, allowing users to efficiently organize and share information while maintaining compatibility across diverse software platforms.

What is a XLSX file?

The XLSX file format is a proprietary spreadsheet format developed by Microsoft Excel. It is part of the Microsoft Office Open XML specification. XLSX files store data in a structured, tabular form, incorporating worksheets with cells arranged in rows and columns. Supporting features like formatting, formulas, and charts, XLSX facilitates the creation of complex spreadsheets. The format employs XML to organize and compress data, enhancing file size efficiency.
