How to Convert Excel to CSV
- 1
Upload Your Excel File
Drag and drop your Excel file (.xlsx, .xls, .xlsm, .xlsb, or .ods) into the upload area, or click to browse your files. The converter processes everything locally in your browser -- no file is uploaded to any server. - 2
Select Your Sheet
If your workbook contains multiple sheets, use the sheet selector to pick the one you want to convert. You can preview the data in each sheet before converting to make sure you have the right one. - 3
Choose a Delimiter
Pick the delimiter that fits your needs. Comma is the standard CSV format, semicolons are common in European systems, tabs produce TSV files, and pipe delimiters work well for data that already contains commas. - 4
Download Your CSV
Review the CSV output and data preview, then click Download CSV for a single sheet or Download All Sheets to export every sheet as a separate CSV file. You can also copy the output directly to your clipboard.

Why Use Excel to CSV Converter?
The Excel to CSV Converter transforms your spreadsheet files into clean, universally compatible CSV format directly in your browser. Whether you are working with modern .xlsx files or legacy .xls workbooks, this tool handles the conversion instantly without uploading data to any server. Your files stay private on your device throughout the entire process.
CSV (Comma-Separated Values) is the most widely supported data exchange format across databases, programming languages, and analytics platforms. Converting from Excel to CSV removes proprietary formatting, formulas, and styling to produce a lightweight, plain-text file that works everywhere. If you need to go the other way, the CSV to Excel converter can rebuild your spreadsheets. For quick data inspection without conversion, try the CSV Viewer to browse and filter your files.
Power users working with multiple data formats will find the full suite of CSV tools useful. The CSV to JSON converter is ideal for preparing data for APIs and web applications. The CSV Merger combines multiple files into one, while the CSV Column Extractor lets you pull out only the columns you need. For broader spreadsheet editing tasks, the Spreadsheet Editor offers a full in-browser editing experience.
How It Compares
Desktop applications like Microsoft Excel and Google Sheets can export to CSV, but they require software installation or a Google account. Online converters often upload your files to remote servers, raising privacy concerns for sensitive business data. This tool runs entirely in your browser using JavaScript, so your spreadsheet data never leaves your device -- no account, no upload, no file size restrictions.
Compared to command-line tools like csvkit or Python scripts using openpyxl, a browser-based converter requires zero setup and works on any operating system. It is especially useful for non-technical users who need a quick conversion without installing software or writing code. For developers who need to transform the resulting CSV further, the CSV to JSON tool and JSON to CSV converter provide seamless next steps in the data pipeline.
