Question 1

How does the CSV to Excel converter work?

Accepted Answer

Simply drag and drop your CSV file or click to upload. The tool automatically detects the delimiter (comma, semicolon, tab) and encoding. You can preview the first 10 rows, then download the converted Excel (.xlsx) file.

Question 2

Is this CSV to Excel converter free?

Accepted Answer

Yes, this tool is completely free with no signup required. You can convert as many CSV files as you need without any limitations.

Question 3

Is my data secure when using this converter?

Accepted Answer

Absolutely. Your data never leaves your browser. All processing happens 100% client-side on your device. We never upload, store, or access your files on any server.

Question 4

What is the maximum file size supported?

Accepted Answer

The converter supports CSV files up to 10MB. For larger files, we recommend using ElyxAI directly in Excel which handles files of any size.

Question 5

What delimiters are supported?

Accepted Answer

The tool supports all common delimiters: comma (,), semicolon (;), tab, and pipe (|). It auto-detects the delimiter, but you can also manually select one if needed.

Question 6

What file encodings are supported?

Accepted Answer

The converter automatically detects and handles common encodings including UTF-8, UTF-16, ISO-8859-1 (Latin-1), and Windows-1252. Special characters and accents are preserved.

Question 7

Can I preview my data before downloading?

Accepted Answer

Yes! After uploading your CSV file, you will see a preview table showing the first 10 rows of your data. This lets you verify the delimiter detection and data formatting before downloading.

Question 8

Will the Excel file work in Google Sheets?

Accepted Answer

Yes, the generated .xlsx file is compatible with Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications that support the Excel format.

Question 9

Why is my CSV not being parsed correctly?

Accepted Answer

If auto-detection fails, try manually selecting the correct delimiter from the dropdown. Also ensure your CSV uses consistent formatting throughout the file.

Question 10

What browsers are supported?

Accepted Answer

The converter works in all modern browsers including Chrome, Firefox, Safari, and Edge. It also works on mobile devices (iOS and Android).

Question 11

Can I convert multiple CSV files at once?

Accepted Answer

Currently, you can convert one file at a time. For batch conversions and advanced features, try ElyxAI directly in Excel.

Question 12

How is this different from just opening CSV in Excel?

Accepted Answer

When you open a CSV directly in Excel, it may not detect the delimiter correctly, especially with European CSVs using semicolons. This tool auto-detects and converts cleanly to a proper .xlsx file.
