Managing Leave with Excel: Why It No Longer Cuts It in 2026

You know the scenario: the team has grown to 15 people, summer is approaching, and someone has just overwritten the shared Excel spreadsheet used for the leave plan. Or worse: two employees have entered the same period because the update hadn't synchronised yet. The leave plan that worked fine with five people becomes a source of errors as the team grows — and a genuine compliance risk.

This article explains why Excel as a leave management tool hits its limits in growing small businesses, what specific problems arise, and what modern tools do better.

The Typical Excel Solution — and Why It Breaks

In many small companies, leave management has run through a shared spreadsheet for years: employees enter their requested dates, the manager approves by email or verbally, and someone updates the sheet. It works — until it doesn't.

Based on experience, the tipping point comes at around 10 to 15 employees. Below that, Excel can still be managed with some discipline. Above it, structural problems emerge that can't be solved by more discipline.

The 5 Biggest Weaknesses of Excel for Leave Management

1. Version Conflicts and Overwrites

As soon as more than one person is working in a shared document simultaneously — whether via SharePoint, OneDrive, or Google Sheets — conflicts arise. Changes get overwritten without anyone noticing. The employee who entered their leave on Friday afternoon finds on Monday that the entry has disappeared — because a colleague had the sheet open at the same time and saved the last version over it.

2. No Reliable Approval Process

In Excel, there is no formal approval logic. The "process" is: employee enters their request, sends an email or flags the manager, the manager nods, someone updates the sheet. This chain is error-prone. Was the leave actually approved? When? By whom? If a dispute arises, there's no documentation at all.

3. GDPR Risks from Shared Files

Leave data constitutes personal data under GDPR — including absence reasons such as sick leave or special leave. When this data sits in a shared Excel sheet that the entire team may have access to, data protection problems emerge: employees can see absence information about colleagues that should not be accessible to them. In the event of a data protection audit, this can become costly.

4. No Audit Trail

Who changed what and when? In standard Excel spreadsheets, this is virtually impossible to reconstruct after the fact. From an employment law perspective, this can be problematic — particularly if an employee disputes whether leave was approved, or if carry-over leave from the previous year is contested.

5. No Mobile Access

Employees in the field, on construction sites, or working from home rarely have direct access to the internal network share where the Excel file is stored. Requests then get made by email or phone anyway — which largely negates the benefit of having a "central" spreadsheet.

What Modern Leave Management Tools Do Better

A dedicated leave management tool — as an Excel alternative — provides structural advantages that cannot be replicated with more discipline or better macros in Excel:

Automatic notifications: When an employee submits a leave request, the responsible manager immediately receives a notification — by email or push notification on their smartphone. No chasing, no forgetting.

Formal approval workflow: Requests are explicitly approved or declined, with a clickable button. The decision is timestamped, logged, and visible to both parties. This creates legal certainty.

Real-time team calendar: All employees can see at a glance who is absent and when — always up to date, without anyone having to update the sheet manually. This makes leave planning within the team considerably easier.

Role-based data privacy: Employees only see what they are permitted to see. Absence reasons remain private; the manager sees all the details, while colleagues only see the fact of the absence.

Mobile access: Leave requests can be submitted and approved from a smartphone — from anywhere, without VPN or network access.

Automatic calculation: Carry-over leave, entitlements following a start date or changes in working hours, annual rollovers — good software calculates all of this automatically and accurately.

TodayOff vs. Excel: A Direct Comparison

Feature	Excel	TodayOff
Submitting a leave request	Manual entry in the sheet	App or web, in seconds
Approval workflow	By email, undocumented	One click, logged
Notifications	None	Automatic via push / email
Team calendar	Maintained manually	Real-time, automatic
Mobile access	Limited	Full (iOS + Android)
Audit trail	Not available	Complete
GDPR compliance	Risky when shared	EU data storage, GDPR-compliant
Carry-over calculation	Manual, error-prone	Automatic
Price	"Free" (hidden effort)	from €1.49 / user / month (up to €2.99 for the Complete Bundle)
Setup time	Hours to days	Minutes

The cost of Excel appears to be zero at first glance — but it is hidden in the time someone spends on manual maintenance, in the errors introduced through manual entry, and in the potential costs of a GDPR violation or an employment law dispute.

When Does Switching Actually Pay Off?

The answer is: sooner than most people think. From as few as 8–10 employees, the maintenance effort for Excel regularly exceeds the cost of dedicated software. Specifically:

• If you spend more than 30 minutes per week maintaining the leave plan — software for 10 users costs around €30 per month.
• If you regularly receive follow-up questions by email or phone about who is on leave and when.
• If you have field workers or remote employees who don't have easy access to the shared sheet.
• If you need to prove, in the event of a formal warning or termination, when a particular leave was approved.

The Migration Process: Easier Than You Think

A common barrier is the fear of data migration: "We have everything in Excel already — how do we get it into a new system?" The good news: modern tools are designed specifically to remove this hurdle.

With TodayOff, you can import your existing leave data from Excel. The process works in three steps:

1. Export from Excel: Save your current spreadsheet as a CSV file.
2. Import into TodayOff: The app guides you through the structured import — employee data, leave entitlements, and existing entries are taken over automatically.
3. Onboard the team: Send your employees an invitation link. Most are up and running within two minutes.

The entire process typically takes under an hour for a team of 15–20 people. After that, manual maintenance is a thing of the past.

What to Look for When Choosing an Alternative

Not every leave management tool is suitable for every company. Pay attention to the following points when making your choice:

EU data storage: Your employee data is only GDPR-compliant if it is stored on EU servers. Ask every provider explicitly about their data centre location.

No hidden costs: Some providers require annual contracts, minimum user numbers, or charge additional modules separately. Look for transparent, month-to-month pricing.

Mobile app: Particularly for small companies, it's essential that the app genuinely works — and isn't just a cut-down mobile view of the desktop version.

Simple onboarding: The more complex the setup, the higher the risk that adoption will fail. Test whether you can set up the software on your own in under 30 minutes.

Conclusion

Excel was a pragmatic solution for leave management in small teams for a long time. With growing companies, increased data protection requirements, and rising documentation obligations, it is no longer an adequate solution today. The good news: switching to dedicated software is faster and cheaper than most people expect — and pays off from just a handful of employees.
