15 Best Free Online CSV to Excel Converter Websites

Here is a list of the best free online CSV to Excel converter websites. CSV (Comma Separated Values) is a file format to store tabular data. This file format is commonly used to store and exchange data between programs. Although CSV is a good format for saving tabular data, Excel provides better options for data analysis, visualization, and presentation purposes.

There are many ways to convert CSV data into a spreadsheet. However, online converters are one of the simplest and quickest solutions to perform this transformation. This post covers 15 websites that can help you convert CSV data into Excel spreadsheets. The CSV to Excel converters on these websites support XLS, XLSX, or both Excel file formats. Most converters ask you to upload CSV files and provide Excel files in the output. Whereas some converters can also take the CSV data that you can directly copy and paste. This allows you to quickly perform your conversion and get the Excel file containing your data. Let’s explore the list and check what these converters offer.
