Why Excel FILTER Function Appears to Skip Rows in Dynamic Arrays
Question details
The user is experiencing an issue where the FILTER function formula is omitting rows from its output, even when the condition evaluates to TRUE for all rows.

- Device & OS
- not provided
- Scenario
- Using the FILTER function to extract specific data into a dynamic array.
- Observed behavior
- The spilled array results appear incomplete, showing only a few results instead of the full matching dataset, usually due to hidden rows in the worksheet.
Before troubleshooting your formula, ensure that you haven't manually hidden any rows in your spreadsheet and check if standard worksheet filters are currently active on the destination rows.
Clear Worksheet Filters to Reveal Hidden Rows
The most common reason a FILTER function appears to skip rows is that the rows within the spilled output range are hidden by a standard worksheet filter applied elsewhere on the sheet.
When the FILTER function spills results into multiple rows, it does not override existing row visibility settings. If the destination rows are filtered out by a traditional worksheet filter, the spilled data will exist but remain invisible to the user. This often gives the illusion that the formula is failing or evaluating incorrectly.
Click on the 'Data' tab located in the top ribbon of your Excel workbook.
Look for the 'Sort & Filter' group and click the 'Clear' button to remove any active filters on the current worksheet.
Select the entire sheet by pressing Ctrl+A, right-click on any row number on the far left side, and select 'Unhide' to ensure no rows are manually hidden.
Check the output range of your FILTER function again. All the matching records should now be fully visible.

Frequently Asked Questions
Why is my FILTER function returning a #SPILL! error instead of skipping rows?
A #SPILL! error occurs when the dynamic array needs to output data, but the destination cells are not empty. You must clear the blocking cells (including spaces or hidden characters) to allow the formula to spill correctly.
Can the FILTER function skip blank rows in my source data?
Yes. You can modify your 'include' argument to exclude blanks. For example, use =FILTER(A2:B10, A2:A10<>"") to return only the rows where column A is not empty.
Why does the FILTER function evaluate to TRUE but return a 0?
If the source cell that matches your criteria is completely empty, the FILTER function will output a 0 in the spilled array instead of a blank space. You can fix this by appending &"" to your formula to force it to return blank text.
Does applying a new filter to the spilled results break the dynamic array?
Applying a standard AutoFilter directly on top of a spilled dynamic array can cause unexpected visual behaviors, such as hiding rows of your formula output. It is recommended to filter the source data or use nested dynamic array formulas instead.
