Differences Between Excel (XLSX) and CSV
- Excel (XLSX): Microsoft Excel's standard format. It can save various formats like font colors, table borders, and function formulas, but the file is heavy and hard to open without specific software.
- CSV (Comma-Separated Values): The simplest form of a text file where data is separated by commas (,). It cannot save formatting, but the size is extremely light, making it a universal format that can be instantly read and written in any environment like Python, databases (DB), and websites.
Why a Two-Way Converter is Needed
- XLSX â CSV: Essential when bulk registering products to websites or online stores, or when lightly extracting data for programming (e.g., AI training data).
- CSV â XLSX: Used when converting raw CSV data downloaded externally into a clean table format (XLSX) that is easy for general office staff to view and edit in Excel.
Prevent Annoying Text Encoding Issues!
Have you ever opened a downloaded CSV file in Excel only to find the text completely corrupted and unreadable? Our converter automatically inserts a special identifier called UTF-8 BOM (Byte Order Mark), ensuring that data in any language opens perfectly in Excel without breaking.
