What is an Excel to CSV converter?
An Excel to CSV converter extracts data from a .xlsx or .xls spreadsheet and saves it as a plain-text .csv file. CSV is the universal format for moving data between apps — databases, CRMs, email marketing platforms, analytics tools, and data pipelines all accept it. Excel is great for formatting and formulas, but when you need raw data, CSV is the right output.
Common use cases: exporting a contact list from Excel to import into Mailchimp, pulling a product catalog into a CMS, preparing data for a Python or SQL workflow, or sharing a clean dataset with a developer who does not work in Excel.
How to convert Excel to CSV
Drop your files. Drag one or more .xlsx or .xls files onto the upload area, or click to browse. You can convert multiple files at once.
Choose sheet and delimiter. If your workbook has multiple sheets, a dropdown lets you pick which one to export. Switch between comma and semicolon delimiters — useful if your data contains commas or if you are importing into European software.
Preview, then download. Click Preview to see the first few rows before downloading. When ready, click the download button — or use Download All to export every file at once.
Does my file leave my device?
No. The converter runs entirely inside your browser. Your files are never uploaded to any server, never stored, and never sent anywhere.
