Excel works fine for project management — until it doesn’t. The question isn’t whether Excel is the wrong tool. It’s whether your project has grown past what a spreadsheet can sensibly handle. This article draws that line clearly.
When Excel isn’t enoughMicrosoft Project Professional 2024Perpetual licence · instant delivery · no subscription
Start here, because dismissing Excel as a project management tool is wrong. Excel is genuinely capable for a wide range of project work, and if your situation fits, there is no reason to buy anything else.
Excel handles these project scenarios well: simple task lists where one person owns the whole plan, budget tracking without schedule integration, straightforward progress reports, and one-off projects with fewer than around twenty tasks and no meaningful interdependencies. If a delay on one task has no knock-on effect on anything else, Excel’s lack of dependency logic is not a problem — it’s just not relevant.
A lot of project managers run small internal projects in Excel their entire careers without issue. That’s not a failure of ambition. It’s using the right tool for the job. The argument for Project starts when the project structure starts working against you — when the spreadsheet is creating problems rather than solving them.
Where Excel starts to break
The failure modes are specific. They don’t announce themselves until a project is already mid-run, which is why people often underestimate them at the planning stage.
Failure mode 1Dependency logic
In Excel, if task B can’t start until task A finishes, you track that relationship manually. Change task A’s end date and nothing updates downstream. In a project with thirty interdependent tasks, one change means manually recalculating the rest of the schedule. Project treats dependencies as live relationships — move any task and the entire downstream plan recalculates automatically.
Failure mode 2Critical path visibility
Excel has no concept of a critical path. You can colour cells and add notes, but the application cannot identify which tasks, if delayed, will extend the project end date. Project calculates the critical path and highlights it. For anything with a fixed external deadline — a client handover, a regulatory submission, a go-live date — this is not optional.
Failure mode 3Resource allocation
Excel tracks who is assigned to what. It does not track whether someone is overallocated across multiple tasks or projects simultaneously. That conflict stays invisible until someone misses a deadline. Project’s resource view shows workload across all tasks and flags overallocations before they become problems.
Failure mode 4Baseline tracking
Excel has no native baseline. You can snapshot a column, but tracking variance against the original approved plan across a live, changing schedule requires a level of manual discipline that rarely survives the first major scope change. Project baselines the plan at approval and tracks slippage automatically from that point forward — without you maintaining it by hand.
The reporting problem
Turning an Excel schedule into a stakeholder-ready Gantt chart or burndown report is a separate piece of work every time someone asks for one. Formatting, updating dates, adjusting the chart range — it’s not difficult, but it’s time that compounds across a long project. Project produces these directly from the live schedule data. The report is always current because it’s generated from the same source as the plan.
The honest comparison
Neither tool is better in the abstract. The right answer depends entirely on what the project requires.

What the upgrade costs — and how it compares
Project Professional 2024 from Software Supplies is £239 — a one-time perpetual licence. You buy it once, it works indefinitely, and there is no annual renewal. Excel is already included in your Office licence, so the comparison is not Excel vs Project as competing costs — it’s whether the incremental cost of Project is justified by what it saves.
Project Professional 2024 — perpetual, one device£239 once
Project Plan 3 — subscription (per year, one user)~£276/year
Project Plan 3 — total over 5 years~£1,380
5-year cost: Project Professional 2024 (perpetual) vs Project Plan 3 (subscription). Break-even at year one.
The subscription route costs more than five times as much over five years. For a single project manager running complex programmes, the perpetual licence pays for itself the moment it prevents one stakeholder report from taking a manual afternoon to produce — let alone avoiding a missed dependency. For more detail on what the subscription plans actually add over the perpetual licence, see the Project Professional 2024 vs Plan 3 comparison.
Signs your project has outgrown Excel
If any of the following describe your current situation, the spreadsheet is working against you.
You maintain a manual “predecessor” column and update it by hand whenever dates shift
The schedule has more than around 30 tasks with interdependencies — even 20 if they’re complex
Two or more people are assigned to overlapping tasks and you’re not certain who has available capacity
You’ve sent a stakeholder an Excel Gantt and spent more than twenty minutes formatting it first
A delay surfaced as a surprise — one that was technically captured in the spreadsheet but never flagged
You’re running more than one project simultaneously and can’t see resource conflicts across them
Someone has asked you for a baseline comparison — what the plan said vs what actually happened — and you’ve had to rebuild it from version history
None of these problems are Excel’s fault. They’re symptoms of project complexity that has moved past what a general-purpose spreadsheet was designed to manage. That’s not a criticism — it’s just where the boundary is.
Yes — but not natively. The standard approach is to build a stacked bar chart and manually format it to look like a Gantt. There are also Excel add-ins that generate Gantt views. The result is a visual representation, not a live schedule: if a task date changes, the chart doesn’t update automatically. Microsoft Project produces a proper Gantt chart directly from the schedule, updates it whenever the plan changes, and lets you filter, highlight the critical path, and export it for stakeholders without reformatting.
Yes. Project Professional 2024 can import task data from Excel using the built-in import wizard. It maps Excel columns to Project fields — task names, durations, start and finish dates, and resources. The import isn’t always perfect for highly customised spreadsheet formats, but it’s a workable starting point that avoids re-entering everything manually. Once imported, you can define dependencies, set a baseline, and let Project take over the scheduling logic from there.
For genuinely small projects — fewer than twenty tasks, no significant interdependencies, one person managing the whole plan — Excel is probably enough and Project would be underused. The value of Project shows up at moderate complexity: once you have dependency chains, shared resources across tasks, or a fixed external deadline you’re accountable to, the scheduling engine earns its cost quickly. The perpetual licence means you’re not paying monthly for those quieter periods between projects either.
Project Standard 2024 covers core scheduling: Gantt charts, task dependencies, critical path, and basic resource management. Project Professional 2024 adds team collaboration features, resource levelling across multiple projects, and integration with Project Server and Project Online for organisations running portfolio-level management. For most individual project managers and small teams, Professional is the version to buy — the collaboration and resource levelling features earn their place quickly on anything beyond single-person project plans.
No. Project Professional 2024 is a standalone perpetual licence that does not require a Microsoft 365 subscription. You need a Microsoft account to activate it through setup.microsoft.com, but that’s a free account — no subscription required. Once activated, Project runs fully offline and doesn’t require any cloud service to function day to day.
Yes, and they complement each other well. Project manages the schedule, dependencies, and resource plan. Excel handles budget modelling, financial reporting, and the kind of freeform data analysis that doesn’t need scheduling logic. Project exports data directly to Excel, so stakeholder cost reports, resource summaries, and earned value data can move between the two without manual re-entry. Most project managers end up using both.
