How to Calculate Employee Review Results Across Multiple Excel Worksheets
Question details
The user needs to create a dynamic report that consolidates employee review records from multiple worksheets, filters them by specific employees and date ranges, and calculates total reviews, failed reviews, and accuracy percentages.

- Device & OS
- not provided
- Scenario
- Generating an aggregated performance report from multiple employee evaluation sheets based on dynamic criteria like employee name and date range.
- Observed behavior
- Data is scattered across multiple sheets, making it difficult to dynamically extract and calculate specific metrics like total reviews and failure rates using standard formulas directly.
Ensure all your individual review worksheets share the exact same column structure and headers, as consistent layout is required for seamless data consolidation.
Consolidate and Filter Data Using VSTACK and FILTER
Use Excel's dynamic array functions to stack multiple sheets into one master list and extract specific records based on your criteria.
In Microsoft 365, dynamic array formulas allow you to combine and analyze data across sheets without using complex VBA macros. VSTACK stacks your arrays vertically, while FILTER isolates the exact records you need.
Use the formula =VSTACK(Sheet1:Sheet3!A2:E100) to stack the data from multiple review sheets into a single array. You can place this in a helper sheet or nest it directly inside your other formulas.
Use the FILTER function to narrow down the stacked data. For example: =FILTER(StackedData, (EmployeeRange=SelectedName)*(DateRange>=StartDate)*(DateRange<=EndDate), "No records").
Wrap your filtered result with the ROWS function, like =ROWS(FilteredResult), to get the total number of reviews matching the criteria.
Use the COUNTIFS function on the column of your filtered data that contains the review scores or status to count the number of failures.
Use a basic mathematical formula to determine the accuracy rate: =(TotalReviews - FailedReviews) / TotalReviews, and format the cell as a Percentage.
Merge Worksheets Using Power Query and Analyze with PivotTables
A robust method for handling large datasets across many sheets without complex nested formulas.
Use WPS Spreadsheet for Advanced Data Analysis
WPS Spreadsheet provides powerful array functions and PivotTable capabilities to easily consolidate, filter, and calculate employee review metrics across multiple worksheets.
- 1. Open your workbook: Launch WPS Spreadsheet and open the file containing your multiple employee review worksheets.
- 2. Consolidate your data: Use the VSTACK function or the built-in Data Consolidation tool under the Data tab to merge your sheets into a master list.
- 3. Apply filters and formulas: Use FILTER, ROWS, and COUNTIFS just like you would in Excel to generate your dynamic employee report based on criteria cells.
- 4. Create a PivotTable: Alternatively, select your consolidated data, go to Insert > PivotTable, and drag your fields to analyze the pass/fail results visually.
Frequently Asked Questions
Can I use 3D references with COUNTIFS across multiple sheets?
No, standard functions like COUNTIFS do not support 3D references (e.g., Sheet1:Sheet3!A1:A10). You must first consolidate the data using VSTACK, Power Query, or a helper summary sheet before applying conditional counts.
How do I create a drop-down list for selecting employees?
Select the cell where you want the drop-down, go to the Data tab, click Data Validation, choose 'List' under the Allow menu, and select the range containing your unique employee names as the Source.
Why is my VSTACK formula returning a #CALC! error?
This usually happens if the VSTACK result is nested inside a FILTER function that finds no matching records based on your criteria (e.g., the employee had no reviews in the selected date range). You can fix this by adding the [if_empty] argument in the FILTER function, like returning 'No data'.
Will PivotTables automatically update when I add new review sheets?
If you use Power Query to append all sheets in a folder, clicking 'Refresh All' on the Data tab will automatically include new sheets. If you manually select a cell range for your PivotTable, you will need to update the data source to include the new sheets.
