Moving from Excel to Calibration Software Without Disruption

In most calibration laboratories, calculations and certificates have been prepared in Excel for years. The habit did not form by accident, because Excel is a flexible and familiar tool. As a laboratory grows, however, the limits of running the work through files become visible. In this article we explain why moving from Excel-based calibration to calibration software comes onto the agenda, and how the move can be made without breaking established habits.

Why do laboratories work with Excel?

Excel is a tool almost everyone knows for doing calculations and arranging tables. Over the years, laboratories have developed their measurement calculations and certificate designs in Excel according to their own needs. These files carry the laboratory's technical know-how and have usually been verified with care. Preparing a template for a new device type is also quick, because there is no need to wait for anyone's support. That is why the idea of leaving Excel behind causes understandable unease in many laboratories.

Problems that appear as the laboratory grows

The problem is not Excel itself but running the work through scattered files. As the volume of work and the number of staff increase, the following difficulties become more frequent:

• File versions: Different copies of the same template circulate on different computers, and it becomes unclear which one is current.
• Permissions: Anyone who can open the file can also change a formula, and an unwanted change may go unnoticed for a long time.
• Traceability: It becomes hard to show afterwards which stages a certificate went through and which data it was prepared with.
• Repeated data entry: Customer and device details are typed separately into the quotation, the intake form, the certificate and the tracking list.

None of these problems stops the work on its own, but together they turn into lost time and a risk of error. When an audit or a customer objection makes it necessary to show how an old certificate was calculated, finding the right file and the right version becomes a job in itself.

What laboratories fear most about the move

The first concern of laboratories considering software is that the spreadsheets they have worked on for years will go to waste. The second is that technicians will slow down on an unfamiliar screen and the work will fall behind. A change in the look of the certificate, and the loss of a design customers are used to, is also raised often. All of these concerns are valid and should be taken seriously when planning the move. A good transition does not force a laboratory to abandon its current setup in a single day.

Another concern is whether verified calculations will give the same result in the new environment. That question should be answered by comparison, not by assumption. Seeing the results of the old and the new setup side by side with the same measurement data is the soundest way to win the team's confidence.

Keep using your existing Excel design

KALDATA offers several methods for creating a certificate template, and one of them is uploading the laboratory's own Excel certificate design. The design you invested in is preserved, and the certificate keeps the look your customers know. Templates are linked to device types, which reduces the need to search through folders for the right one. For other ways of working there are also options such as form-based raw data entry, working together on an online sheet or uploading a ready-made certificate file. The laboratory can start with the method that best suits the way it works.

An online spreadsheet that feels like Excel

Another route is to use the online spreadsheet built into the software. It runs in the browser, requires no additional program, and works much like Excel. Functions can be written with their Turkish or English names, and decimal commas are supported. Data copied from Excel can be pasted in, and Excel files can be imported and exported. For laboratories looking for an online Excel, this is a practical way to carry a familiar way of working into a shared environment.

Familiar features such as multiple sheets, dropdown lists, conditional formatting, charts and frozen panes are available too. When writing a certificate, the technician fills in only the measurement cells, the results are calculated instantly and carried over to the certificate output. Cell and sheet locking helps prevent formulas from being changed by accident. Each certificate keeps its own record, so earlier certificates are not affected even if the template is changed later.

Step-by-step suggestions for the move

Making the move in stages rather than all at once reduces the risk. Every laboratory's circumstances are different, but in general the following order works well:

• Choose a few of your most frequently used device types and start with them.
• Review your existing templates and weed out unused and duplicate files.
• Compare the results of the new template with those of your old file using the same data.
• Run a short trial period with the technicians and collect their feedback.
• As the trial goes smoothly, add the other device types one after another.

Conclusion

Moving from Excel to a calibration program does not mean giving up the know-how built in Excel. The aim is to run the same calculations without version confusion, in a shared environment where formulas are protected and the stages are clear. When a laboratory takes small, measured steps on its path to digitalization, the team adapts to the new setup more easily.
