What is CSV?

CSV, or Comma-Separated Values, is a simple file format used to store tabular data, such as spreadsheets or databases, in plain text. It uses commas to separate values and new lines to denote rows. CSV files are widely used for data exchange between different applications and are easily readable by both humans and machines.

Loss of Formatting

When converting from Excel to CSV, all the formatting (colors, fonts, cell sizes, etc.) is lost since CSV only saves raw data.

Data Type Misinterpretation

Excel may interpret certain data types (like dates or currency) differently than how they appear in a CSV, leading to potential data errors.

Special Characters and Encoding Issues

CSV files may not handle special characters (e.g., accents or symbols) well, which can result in corrupted data if proper encoding (like UTF-8) is not used.

Inconsistent Delimiters

Different applications may use different delimiters (like semicolons instead of commas), causing confusion and errors when importing CSV files into other systems.

What are the differences between XLSX and XLS?

File Format

XLSX is the modern file format used by Microsoft Excel, introduced with Excel 2007, and is based on the Open XML standard. In contrast, XLS is the older binary file format used by earlier versions of Excel up to 2003.

File Size

XLSX files are generally smaller in size compared to XLS files because they use Zipping compression, making it more efficient for storage and sharing.

Data Capacity

XLSX supports a significantly larger amount of data, allowing for up to 1,048,576 rows and 16,384 columns per worksheet, while XLS is limited to 65,536 rows and 256 columns.

Features and Functions

XLSX files support newer features and functions available in Excel 2007 and later versions, such as improved charting tools, Sparklines, and enhanced formulas. XLS files do not have access to these advanced features.
