Convert XLSX to CSV

XLSX files are Excel files that use the Office Open XML format, which Microsoft introduced with Excel 2007.

Like XLS files, XLSX files can have multiple sheets, and each sheet can contain multiple rows and columns of data. They offer several advantages over the older XLS format.

Key features of XLSX files include:

• Better compression, resulting in smaller file sizes
• Enhanced security features, including password protection and digital signatures
• Better recovery from file corruption
• Support for more rows (1,048,576) and columns (16,384) per sheet
• Works with a wide range of applications and programming languages

XLSX files are based on XML and ZIP technologies, making them easier for third-party software to read and write.

Comma-separated values (CSV) is a simple and popular format for storing tabular data. It's easy to read and create, making it a go-to choice for many.

Row delimiter

The row delimiter separates each row in the CSV data. It's usually a new line character (LF) or a carriage return plus a new line character (CRLF).

We'll automatically detect and parse the rows correctly, so you don't need to worry about it.

Value separator

The value separator splits each value within a row.

For CSV files, it's typically a comma, but it can vary depending on the software used to create the file. We support these separators:

• Comma ,
• Tab \t
• Pipe |
• Hash #
• Semicolon ;

Character encoding

The character encoding of your CSV file might differ based on the software you used to create it.

If you're not sure about the character encoding, don't worry. We'll try to guess it automatically if it's not specified.
