Excel (XLSX) files are based on the Office Open XML format, which is a zipped, XML-based file format developed by Microsoft.
CSV (Comma-Separated Values) is a simple file format used to store tabular data in plain text format, with values separated by commas.
While Excel files can store complex calculations, charts, and styling, CSV files are lightweight and widely compatible across different systems and applications.
Converting from Excel to CSV creates a simplified version of your data that can be easily imported into databases, programming languages, and other software.
CSV files are particularly useful for data exchange between different systems because of their universal compatibility and simplicity.
Technical Insight 🔍
Converting Excel to CSV involves extracting tabular data from Excel's complex structure and reformatting it into a simple, delimited text format.
Excel conversion tools use libraries like pandas, openpyxl, or xlrd to read Excel's binary format and extract cell values from worksheets.
During conversion, formulas are calculated to their final values, and only the resulting data is transferred to the CSV file.
Advanced converters can handle multiple worksheets by converting each to a separate CSV file or merging them with appropriate identifiers.
While Excel supports complex formatting and multiple data types, CSV stores everything as text and relies on proper escaping for special characters like commas within fields.
