Free employee schedulers for Microsoft Excel and Apache OpenOffice Calc are highly cost-effective tools for small businesses managing under 25 hourly employees. Instead of paying for subscription software, managers use these pre-formatted spreadsheets to calculate hours, layout weekly shifts, and ballpark labor costs as a percentage of sales.
Because OpenOffice Calc is fully compatible with Excel files, you can open, edit, and save .xls or .xlsx scheduling templates across both platforms seamlessly. Where to Find Free Pre-Made Templates
You do not need to build a template from scratch. Several trusted providers offer comprehensive, downloadable scheduling spreadsheets that function perfectly in both programs:
Vertex42 Shift Schedule Template: Provides clean, 24-hour shift grids where cells can be shaded or given specific task codes to accommodate rotating schedules.
Smartsheet Basic Staff Schedule Template: Features a single, easy-to-read table layout allowing you to assign employee names, IDs, roles, and specific shift slots.
OpenOffice Extensions & Templates Library: Offers Native .ots (OpenOffice spreadsheet template) files explicitly optimized for OpenOffice Calc without formatting conversion errors. Core Built-In Functions to Use
If you choose to customize your template, rely on these exact formulas to automate your tracking across both Excel and OpenOffice Calc:
COUNTA: Counts active text blocks. Use it to tally up how many shift slots (marked with an “X”) an employee is assigned to determine total time.
COUNTIF: Tracks coverage. Use it to scan a specific day to verify that your morning, afternoon, and night blocks have at least one person assigned.
SUMIF: Streamlines payroll totals. This function matches an employee’s name across multiple schedules and sums up all their total worked hours for a complete pay period. Standard Layout Design
Most functional spreadsheet schedulers are built around a uniform structure:
Column A: Reserved strictly for employee names, roles, and unique IDs.
Row 1 & 2: Display the date fields alongside specific time or shift blocks (e.g., 8:00 AM–4:00 PM).
Final Column: Houses automated formulas calculating the total cumulative weekly hours per person.
Data Validation Dropdowns: Implemented inside shift cells to let you pick “Morning”, “Evening”, or “Sick Day” instead of typing text manually.
Conditional Formatting: Automatically changes the background cell color (e.g., highlighting a cell red if an employee goes into overtime or green to show an active working shift). Key Spreadsheet Limitations
While a free spreadsheet setup removes overhead costs, it does present noticeable bottlenecks as your team grows: Shift Schedule Template – for Excel – Vertex42
