Frequently Asked Questions

How do I convert a CSV file to Excel without losing data?

Use the Softstribe CSV to Excel converter. Upload your .csv file and click Convert. The tool generates a properly formatted .xlsx file that preserves all rows, columns and data types. The conversion runs in your browser — your data never leaves your device.

Why does my CSV look wrong when I open it in Excel?

Excel sometimes misinterprets CSV delimiters (commas vs. semicolons) or treats numbers with leading zeros (like postcodes) as numbers. Using the Softstribe converter ensures the data is correctly structured as an Excel workbook.

Can I convert a CSV with special characters or different encodings?

The tool supports UTF-8 encoded CSV files, which handles most international characters including accented letters, Chinese, Arabic and more. Files saved with older encodings (like Windows-1252) may show garbled characters.

What is the maximum CSV file size I can convert to Excel?

Since conversion happens in your browser, the limit is your device's memory. CSV files up to 50MB (typically millions of rows) convert reliably on modern computers.
