2. What is Better: Modern or Legacy?   It was shared: Short answer- LEGACY Excel connector uses OLEDB to open Excel files while MODERN uses Aspose Engine.  The main difference between these two engines is performance and memory usage when working with large Excel files. The Modern Engine uses less memory and performs better than the Legacy Engine. Also, the Modern Engine can open Excel Files with more than 255 columns.
