I am trying to search for a specific value across a wide range of columns, not just one. It is basically a horizontal and vertical search combined. Can I use a combination of Index and Match to pull a value when I don't know which column it resides in? The data is set up in a large matrix and I need a way to scan the whole grid for a match.
Performing a two-dimensional search in Excel is accomplished by using the INDEX function combined with two MATCH functions, where the first MATCH determines the row position and the second identifies the column position within the range.

You can perform a two-dimensional search by nesting index and match functions to identify both the row and column coordinates.
- Use MATCH to find the row index of your target value.
- Use a second MATCH to find the column index across your header range.
- Reference these coordinates within your primary INDEX function to pull the final result.
- Ensure your ranges are locked to prevent errors during the calculation.
You should use an XLOOKUP function with an array of values to search across the entire grid efficiently. By nesting a secondary match or using the array capability, you avoid the security risks associated with volatile functions like INDIRECT in large, audit-heavy workbooks.
I once had to scrub a massive financial ledger that had been corrupted by manual entry across hundreds of columns. It took me a full afternoon to realize that forcing a traditional index match was essentially creating a ticking time bomb for the reporting accuracy.
I eventually moved the entire structure into a Power Query flat file because trying to scan a grid horizontally and vertically is just asking for a pivot error when someone eventually inserts a new column. Moving the data into a tabular format solved the searching issue permanently and made the entire compliance trail much easier to follow.
The XLOOKUP function is superior to legacy Index Match combinations because it natively handles matrix-wide searches without requiring complex array syntax. XLOOKUP is more resilient to structural changes in your data grid, as it evaluates columns and rows independently while maintaining a cleaner formula logic that aligns with current best practices for data integrity.
Why are you keeping your data in a massive grid format instead of normalizing it into a proper flat table? Storing data this way is a significant vulnerability for data loss and makes querying difficult for anyone who inherits your file.
If you must keep this structure, frankly, you are just making your life harder for no reason. Just unpivot the data in Power Query and use a standard filter or a simple VLOOKUP. It is the only way to ensure your report doesn't break the moment a user accidentally moves a cell.
To effectively query a multidimensional range, you should leverage the XLOOKUP function with a nested filter or index approach. When dealing with large matrices, the primary challenge is identifying the intersection point between a row and a column without creating a brittle spreadsheet that breaks under heavy computation. By using INDEX combined with two MATCH functions—one looking down the vertical axis and one across the horizontal axis—you establish a dynamic link that is significantly more robust than legacy methods.
For instance, if your data matrix spans cells B2 to Z100, you would define the row match based on a unique identifier and the column match based on your specific criteria. This approach relies on precise array definitions. If the matrix size is variable, you might consider using named ranges to ensure the search remains accurate even if you append new data points. It is crucial to remember that exact match modes are preferred to avoid erroneous data pulls in financial modeling, where precision is paramount. While Power Query is technically the more sophisticated professional tool for data transformation, a well-constructed INDEX-MATCH-MATCH formula remains the industry standard for on-the-fly analytical lookups within the grid environment. As long as your array dimensions remain consistent, this method will provide the speed and reliability needed for high-stakes modeling without the overhead of external data connections.
