Convert CSV to an Excel Spreadsheet
Opening a CSV file directly in Excel often goes wrong: everything lands in one column, or accented and non-Latin characters turn into gibberish. Paste your CSV or choose a file, and this tool creates a proper .xlsx workbook with every value in its own cell and all characters intact.
The delimiter is detected automatically, quoted values are read correctly, and numbers are stored as numbers so you can calculate with them right away. Codes with leading zeros stay text. The file is created in your browser — nothing is uploaded.
Why Use This CSV to Excel Converter?
- Correct columns for comma, semicolon, tab and pipe files
- No broken characters — Unicode text stays intact
- Numbers stored as numbers, codes with leading zeros kept as text
- Created in your browser — nothing is uploaded
How to Convert CSV to Excel
- Paste your CSV data or choose a .csv file
- Check the preview and, if needed, pick the delimiter
- Click "Download Excel" to save the .xlsx file
Frequently Asked Questions
Is this CSV to Excel converter free?
Yes, it is completely free and has no limits on the number of files.
Why does my CSV open in a single column in Excel?
Excel guesses the delimiter from your system's regional settings, so a comma-separated file can end up in one column (or a semicolon file in Europe). This converter detects the delimiter from the data itself and puts every value in its own cell.
Will leading zeros be removed?
No. Values such as 00123 or phone numbers are kept as text exactly as in the CSV. Only plain numbers are stored as numbers, and you can turn that off too.
Is my data uploaded anywhere?
No. The Excel file is created entirely in your browser; your data never leaves your device.
