A CSV (Comma-Separated Values) file is a simple text file format that stores tabular data. Each line in the file is a row of data, and columns are separated by a specific character, usually a comma. CSV files are widely used for exchanging data between different systems and applications.
You can create a CSV file from most spreadsheet applications like Microsoft Excel or Google Sheets by using the "Save As" or "Export" option and selecting the CSV format. You can also create a CSV file manually with any text editor by separating your values with commas.
An online CSV viewer like ours offers several advantages: no software installation required, instant access from any device, fast data processing, and a user-friendly interface to easily visualize your CSV data as a structured table.
