How to Add a Name Filter to LET and VSTACK Formulas
Question details
Combine multiple tables into one, remove any blank rows, and filter the combined dataset by an assigned person's name using dynamic array formulas.

- Device & OS
- not provided
- Scenario
- Distributing tasks across individual employee sheets by automatically pulling only their assigned tasks from multiple master tables.
- Observed behavior
- The user needs a dynamic formula that successfully nests VSTACK, FILTER, and TAKE within a LET function to clean and conditionally display data.
Ensure your source data is formatted as Tables (e.g., Table1, Table2) and that your spreadsheet software supports dynamic array functions like LET, VSTACK, and FILTER.
Use FILTER and TAKE Functions inside a LET Formula
By defining variables within a LET function, you can cleanly stack multiple tables, remove blank rows, and filter the final output by a specific column.
The LET function allows you to define variables for intermediate calculation steps, making complex formulas easier to read and faster to calculate.
In this solution, we will stack the tables, filter out empty rows from the first column, and then apply the final name filter.
Start your formula with =LET(header, Table1[#Headers], stack, VSTACK(Table1, Table2, Table3)...). This isolates the headers and stacks all your master tables into a single variable named 'stack'.
Add a variable to clean empty rows: cleaned, FILTER(stack, TAKE(stack,,1)<>""). This filters the 'stack' array to exclude rows where the first column is empty.
Define the final result by filtering the 'cleaned' array: result, VSTACK(header, FILTER(cleaned, TAKE(cleaned,,1)="Maria One")). This evaluates the first column for the name 'Maria One' and stacks the header row on top.
Close the formula and press Enter. The complete syntax is: =LET(header,Table1[#Headers],stack,VSTACK(Table1,Table2,Table3),cleaned,FILTER(stack,TAKE(stack,,1)<>""),result,VSTACK(header,cleaned),VSTACK(header,FILTER(cleaned,TAKE(cleaned,,1)="Maria One"))). The filtered tasks will automatically spill down the sheet.
Easily Manage Dynamic Arrays with WPS Spreadsheet
WPS Spreadsheet fully supports modern dynamic array functions including LET, VSTACK, and FILTER, allowing you to seamlessly consolidate and filter large datasets.
- 1. Open your workbook: Launch WPS Spreadsheet and open the file containing your master task tables.
- 2. Select the target cell: Click on the top-left cell in the employee worksheet where you want the filtered data to appear.
- 3. Enter the formula: Paste your complete LET formula into the formula bar and press Enter to instantly spill the filtered results.
Frequently Asked Questions
What if my LET or VSTACK function returns a #NAME? error?
A #NAME? error usually means your current spreadsheet software version does not support these newer dynamic array functions. Ensure you are using the latest version of WPS Office or Microsoft 365 to gain access to these functions.
How do I remove the header from the final output?
If you do not want the headers to be repeated in the final result, change the final step in your LET function. Instead of nesting it in another VSTACK, simply return FILTER(cleaned, TAKE(cleaned,,1)="Maria One") as your final output.
Can I filter by a different column instead of the first one?
Yes. The TAKE function targets the first column by using the number 1 (e.g., TAKE(cleaned,,1)). To filter based on data in the second column, simply change the parameter to TAKE(cleaned,,2).
