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.
