Critical spreadsheets · Transformation

Keep Excel where it works. Replace what has become risky.

A spreadsheet becomes critical when it coordinates several people, controls approvals or drives decisions. GE2Smart assesses what can stay in Excel and what would work better in a business application.

The warning signs

Your spreadsheet may already be an application — without the safeguards.

A spreadsheet can be ideal for a one-off analysis. It becomes fragile when it runs a daily process involving several users, deadlines or important decisions.

01

Multiple versions circulate

Copies are emailed or saved in different folders, with no certainty about which version is authoritative.

02

Formulas become critical

An edited cell or moved column can distort a calculation without a clear warning.

03

Responsibilities are hard to separate

Several people use the file, but access rights, process steps and approvals are difficult to organise.

04

History is hard to reconstruct

It is difficult to trace an approval, a previous value or responsibility for a change.

Does this spreadsheet really need replacing?

Keep it
For individual analysis or a one-off calculation, improving the file may be enough. Custom software is not an end in itself.
Structure the process
Concurrent entry, distinct permissions and traceable approvals justify considering a shared application.
Prepare the scope
List users, essential formulas and recurring errors. Start from an anonymised example, not sensitive data.
What can change

Keep the useful logic. Add the missing safeguards.

The goal is not to reproduce every cell. It is to identify the data, rules and decisions that justify a proper application.

IMPORT

Migration and cleansing

Review columns, duplicates, inconsistent values and rules hidden in the file.

DATA

One shared database

Structured reference data, accessible according to each user’s permissions.

FORM

Guided data entry

Validation, lists, required fields and automatic calculations help reduce errors.

TRACE

Traceable history

Creation, edits, approvals and comments remain traceable.

AUTO

Reminders and documents

Notifications, deadlines and PDFs can be generated without repetitive handling.

EXPORT

Controlled exports

Excel and CSV remain available for analysis without becoming the operational database again.

Illustrative example

A sales tracking file that the whole business now depends on.

Before

The file contains customers, amounts, deadlines, owners, statuses and comments. Five people use it, but only its creator understands all the formulas.

Smart Tool

The application imports the useful data, provides role-based forms, automates calculations, retains history and flags blocked stages.

Desired outcome

Management has a reliable operational view, teams can work simultaneously and exports remain available for one-off analysis.

Related use cases

Concrete scenarios, not an abstract feature list.

Each example starts from an existing way of working, describes a possible tool and states the outcome to aim for.

How we move forward

Build quickly, without building blind.

The prototype reduces risk. Framing data, access rights and exceptions protects the move into production.

01

Review the file

Identify the useful sheets, rules, dependencies and actual usage.

02

Define reference data

Resolve duplicates and ambiguous fields before migration.

03

Build the working journey

Users enter and approve information in screens suited to their roles.

04

Switch progressively

Testing and a migration plan help preserve the history and continuity of work.

Outcomes to aim for

Value should be visible in the daily work.

01One authoritative version of the data

02Fewer data-entry and formula errors

03Concurrent work with controlled access

04Continuity when the spreadsheet’s creator leaves

Frequently asked questions

Before framing your project.

The answers stay general. Your data, risks and constraints determine the final scope.

Can we migrate all our existing data?

Often, yes, but it must first be checked. Duplicates, free-text cells and incomplete histories need to be qualified before import.

Will we still be able to export to Excel?

Yes. The aim is to make daily operations reliable, not to prevent exports for analysis or information exchange.

What happens to macros?

Their business purpose is reviewed. Some become server-side rules, automations or calculations; others may be unnecessary once the limitations they worked around have been removed.

How long does migration take?

It mainly depends on data quality, hidden rules and the agreed scope. A prototype can be quick, but migration still needs careful preparation.

When is it better to keep Excel?

Keep it for one-off analysis, simulations or simple tracking with manageable rules. The diagnostic first checks whether better organisation of the file and permissions is enough. Custom software becomes useful when roles, approvals, data exchanges and traceability exceed that setup.
