Convert XLS to CSV

XLS files are Excel files that use the Binary Interchange File Format (BIFF), which was the default format for Excel versions 97-2003.

XLS files can contain multiple sheets, and each sheet can contain multiple rows and columns of data. They support various data types, including text, numbers, dates, and formulas.

Key features of XLS files include:

• Compatibility with older versions of Excel and other spreadsheet software
• Ability to store formatting information, charts, and macros
• Smaller file size compared to newer formats like XLSX
• Limited to 65,536 rows and 256 columns per sheet

While XLS files are still widely used, they are gradually being replaced by the more modern XLSX format.

Comma-separated values (CSV) is a simple and widely used format for storing tabular data. It is human-readable and easy to generate and parse.

Row delimiter

The row delimiter is the character used to separate each row in the CSV data. This is usually a new line character (LF), or a carriage return plus a new line character (CRLF).

We will automatically detect this and parse the rows correctly.

Value separator

The value separator is the character used to separate each value inside a row.

For CSV files, as the name implies it is usually a comma, but it can be different depending on the software used to generate the CSV file, we support the following separators:

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

Character encoding

Depending on what software you used to generate the CSV file, it might have a different character encoding

If no character encoding is specified we will automatically try to guess it, so you don't have to worry about it if you're unsure.
