- Sebelum ni, kita ada LOOKUP, HLOOKUP & XLOOKUP. Pendek kata, XLOOKUP ni fungsi pencarian terbaru yang diperkenalkan oleh Microsoft.
- VLOOKUP & HLOOKUP masing-masing mempunyai kelemahan dimana kedua fungsi tersebut terbatas dengan pencarian vertical atau menegak dan horizontal atau mendatar.

- Highlight its core features like:
- Ability to search in both directions.

- Built-in error handling with an
if_not_found argument.
- Searching from either end of a dataset.
3. XLOOKUP Syntax and Explanation
- Break down the XLOOKUP formula:
=XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode], [search_mode])
- Explain each argument with simple examples:
- lookup_value: The value you want to search.
- lookup_array: The range where you’ll search for the value.
- return_array: The range that contains the data you want to return.
- if_not_found: What to show if the value isn’t found (optional).
- match_mode: Exact match, approximate match, wildcard support.
- search_mode: Search from first to last or last to first.
4. Step-by-Step Examples
- Example 1: Basic Lookup
Demonstrate a simple lookup, such as finding a product price from a list.
- Example 2: Handling Errors
Show how the if_not_found argument works by returning custom text when no match is found.
- Example 3: Partial Matches and Wildcards

- Example 4: Reverse Lookup
Demonstrate XLOOKUP returning values from the left side of the lookup range.
5. Comparing XLOOKUP with VLOOKUP and HLOOKUP
- Offer a side-by-side comparison:
- Why XLOOKUP is more powerful than VLOOKUP.
