Why Choose Google Sheets for Your Timesheets App Data?
Google Sheets already powers countless business operations because it's accessible, collaborative, and free. Your existing timesheet data lives there, formatted in rows and columns that track employee hours, projects, and dates. The challenge isn't the data—it's the interface.
Limitations of Spreadsheet-Only Workflows
Spreadsheets create friction for time tracking that mobile apps eliminate:
- Tiny cells make data entry painful on phones and tablets
- No offline access when employees work at remote job sites
- Manual calculations prone to formula errors
- No GPS verification for clock-in/out locations
- Photo documentation requires separate systems
- Real-time visibility requires constant refreshing
When field workers call the office to report hours, someone must transcribe that data into the spreadsheet. This creates administrative burden and introduces errors at every handoff point.
The Case for Keeping Google Sheets as Your Backend
Abandoning Google Sheets entirely means losing familiar tools and rebuilding workflows from scratch. The smarter approach: keep your spreadsheet as the data source while adding a mobile-friendly interface on top.
Google Sheets handles 10 million cells with real-time collaboration features your team already knows. Rather than migrate data, connect it to a proper application layer that makes entry and viewing effortless across devices.
Setting Up Your Employee Timesheet Template in Google Sheets
Your spreadsheet structure determines how smoothly the app connection works. Before connecting to Adalo, prepare your data foundation properly.
Essential Columns for Time Tracking
A functional timesheet requires these core columns:
- Order_ID: Unique identifier for each entry (use ARRAYFORMULA to auto-generate)
- Employee_Name: Text field for the worker's name
- Date: Formatted as YYYY-MM-DD for consistent parsing
- Start_Time: Time value (not text) for clock-in
- End_Time: Time value for clock-out
- Hours_Worked: Calculated field or manual entry
- Project_Name: Text or dropdown selection
- Notes: Free-form text for additional context
Use underscores instead of spaces in column headers. This prevents parsing errors during the connection process.
Data Formatting Best Practices
Clean data imports cleanly. Follow these rules:
- Remove all merged cells (Select All → Format → Merge Cells → Unmerge)
- Ensure no empty rows between data entries
- Use consistent date formats throughout (YYYY-MM-DD works best)
- Keep one data type per column—don't mix dates with text
- Place headers in Row 1 only
For best performance beyond 100,000 rows, archive old entries to a separate sheet before building the app.
Introducing Adalo: Your Go-To No-Code App Builder for Timesheets
Adalo transforms how businesses approach application development. Instead of hiring developers or learning to code, you visually assemble screens and components using drag-and-drop tools.
Why No-Code Matters for Business Apps
Traditional timesheet app development costs $40,000-60,000 in the first year plus ongoing maintenance. No-code platforms deliver 90% faster development cycles, turning months of coding into weeks of visual building.
The productivity gains compound: organizations report 10x faster application delivery compared to traditional coding. For timesheet apps specifically, this means deploying a working solution before the next payroll cycle rather than next quarter.
What Makes Adalo Different
Unlike web-only builders that create glorified spreadsheet views, Adalo produces true native iOS and Android apps with:
- Camera access for photo documentation
- GPS location capture for job site verification
- Push notifications for timesheet reminders
- Native performance without web wrapper limitations
The platform maintains 99% app uptime, ensuring your timesheet tracking stays operational when payroll deadlines arrive.
Connecting Your Google Sheet Data to Adalo
The connection process requires minimal technical knowledge. SheetBridge handles the complexity automatically.
Creating the Connection with SheetBridge
SheetBridge provides the fastest path from spreadsheet to app:
- Navigate to sheetbridge.adalo.com
- Authenticate with your Google account
- Select your timesheet spreadsheet
- Review the auto-detected schema (Employee_Name as text, Date as date, etc.)
- Complete the import
The entire process takes 30 minutes for straightforward timesheets. SheetBridge automatically detects column data types and creates corresponding Adalo Collections.
Understanding Real-Time Sync
Changes flow both directions automatically:
- Edits in Google Sheets appear in the app within seconds
- App submissions write back to your spreadsheet immediately
- No manual sync buttons or scheduled refreshes required
This bidirectional sync lets power users continue working in spreadsheets while field workers use the mobile app. Both access the same underlying data.
Alternative Connection Methods
For advanced scenarios, Adalo offers additional options:
- Zapier integration: Connect timesheets to payroll systems, Slack, or 5,000+ other apps
- External Database Collections (external REST APIs): Advanced external data connections (available on Professional and above at $52/month annual billing
- Collections API (programmatic access to Adalo collections): Available on Team/Business plans
Note that Zapier's free tier uses 15-minute polling intervals. For instant triggers, upgrade to paid plans or stick with SheetBridge for real-time sync.
Designing Your Employee Timesheets App Interface
With data connected, build the visual interface employees interact with daily. Adalo's canvas works like a design tool—drag components, position them, and connect to data.
Building the Time Entry Form
Create a screen for submitting new timesheet entries:
- Add Date Picker component for selecting the work date
- Include Time Selectors for start and end times
- Use Dropdown for project selection (populated from Projects collection)
- Add Text Input for notes
- Configure Submit button to create new timesheet record
Form validation prevents incomplete submissions. Set required fields and format rules directly in component properties.
Creating the Timesheet List View
Employees need to see their submitted hours. Add a Custom List component:
- Set data source to Timesheets Collection
- Filter by logged-in employee
- Display date, project, and hours worked
- Enable tap-through to detail screens
- Add search/filter for finding specific entries
Consider using app templates as starting points. The Task Management template provides pre-built time tracking workflows, reducing build time by 50-75%.
Implementing Core Functionality: Time Tracking & Submission
The interface needs logic to function properly. Adalo handles this through Actions and Formulas.
Automatic Hours Calculation
Rather than manual entry, calculate hours worked automatically:
- Store Start_Time and End_Time as separate fields
- Create a custom formula: (End_Time - Start_Time)
- Display calculated result in Hours_Worked field
- Update totals in Google Sheets via sync
This eliminates math errors and ensures consistent calculations across all entries.
GPS Location Capture
For field service companies, location verification matters. On the Professional plan:
- Add GPS Location component to timesheet form
- Configure to auto-capture on submission
- Store latitude/longitude with each entry
- Display job site location in list views
One HVAC company saved 15 hours weekly by eliminating phone calls and gaining GPS verification for job site disputes.
Photo Documentation
Add File Upload components for visual proof of work:
- Set allowed file types to camera uploads
- Store images with corresponding timesheet entries
- Display thumbnails in list views
- Enable full-size viewing in detail screens
Managing Employees and Approvals with Your Timesheets App
Multi-user systems require role-based access. Employees see their own timesheets; managers see everyone's.
User Authentication Setup
Configure login/signup screens:
- Email/password authentication built-in
- Social login options (Google, Apple)
- User records linked to timesheet entries
- Automatic filtering by logged-in user
Each employee creates an account, and their submitted timesheets link to their user profile automatically.
Building Manager Dashboards
Create admin screens for supervisors:
- List all employees' timesheet submissions
- Filter by date range, employee, or project
- Calculate weekly/monthly totals
- Flag entries requiring attention
- Export data for payroll processing
