FAQ

What CSV formats are supported?

The tool supports standard CSV files with comma-separated values. It automatically detects the delimiter and handles common variations including files with headers, quoted fields, and different line endings. UTF-8 encoding is recommended for best compatibility.

Can I convert CSV files with multiple sheets?

The current version converts your CSV data into a single Excel sheet named "Sheet1". If your CSV contains data that should be split into multiple sheets, you would need to separate it into different CSV files and convert them individually.

Will my data formatting be preserved?

The converter preserves all data values and structure. However, advanced Excel formatting like colors, fonts, or formulas from the original CSV are not preserved since CSV is a plain text format. Numbers and text are maintained exactly as they appear in your CSV file.

Is there a file size limit?

Yes, the tool supports files up to 100MB in size. For very large files, the conversion may take a few moments depending on your device performance. All processing happens in your browser, so your data never leaves your computer.
