Which is Faster: VLOOKUP or XLOOKUP?
Compare the performance and speed differences between VLOOKUP and XLOOKUP functions in Excel.
Complete Guide
Everything you need to know about which is faster: vlookup or xlookup?
Overview
XLOOKUP is generally faster than VLOOKUP, especially with large datasets. XLOOKUP uses more efficient algorithms and doesn't require sorting data for approximate matches. However, the speed difference depends on your data size, Excel version, and specific use case.
Performance Benchmarks
In tests with 100,000+ rows, XLOOKUP typically performs 20-40% faster than VLOOKUP. The performance gap widens with larger datasets and complex lookup scenarios. XLOOKUP's efficiency comes from its modern algorithm design and optimized memory usage.
Why XLOOKUP is Faster
XLOOKUP uses advanced indexing and doesn't need to scan entire table arrays like VLOOKUP. It can perform bidirectional lookups without additional processing, and its error handling is more efficient.
When Speed Differences Matter
For small datasets (under 1,000 rows), the speed difference is negligible. Performance becomes noticeable with 10,000+ rows or when using multiple lookup formulas across large workbooks.
✨Best Practices
- Use XLOOKUP for large datasets when available (Excel 365/2021)
- Consider INDEX-MATCH as a faster alternative to VLOOKUP in older Excel versions
- Optimize VLOOKUP performance by using exact match (FALSE) and sorted data
- Test performance with your specific data size and complexity
