CSV to XLSX Online Converter


A Comma-Separated Values (CSV) file is a widely-used data format, appreciated for its simplicity and wide compatibility. It is designed to store tabular data in a structure of columns and rows. The first line of a CSV file describes the column headers of the table (their names), and each subsequent line contains the data values of those columns, separated by commas.
On the other hand Microsoft Excel utilizes the XLSX file format, an open XML spreadsheet format, to handle complex data operations with calculation tools. By converting CSV files to XLSX format, you gain access to Excel's user-friendly graphical interface.
