WEEK 3 : Unknown zone mission
The Abyss Surveys
The Nautilus is crossing a new mapping area. Underwater data is flooding in: coordinates, resources, oxygen levels, sonar anomalies… Raw and disorganised, this data is unusable. Help the crew turn this chaos into actionable information!
Your turn
In Excel, a keyboard shortcut allows you to transform a raw list into a table, but which one is it? Click on the correct key combination on the keyboard in front of you.
Let's go!
finish
Transform a data range into a table offers many advantages: automatic sorting and filters, uniform formatting, simplified calculations, and automatic extension when new rows are added. It is often the first best practice to adopt before analysing data in Excel.
Congratulations, the collected data now form a more usable base. Tomorrow, the crew will be able to start examining them in more detail.

Formulas
Scientists can now quickly find the information they need and continue their work in better conditions. However, the most difficult part is not yet over: some data will need to be enriched before they can be used effectively.
You use Excel to analyse data… but you also need to choose the right formula at the right time. Some allow you to calculate, others to count or search for information. Will you be able to recognise their usefulness? Match each formula to its function.
to finish
Formulas are at the heart of Excel's power. Some allow you to search for information, others to count, calculate or automate decisions. The more you master the functions suited to your needs, the less time you spend performing manual processes. Want to go further? Discover the possibilities offered by RECHERCHEX:
Thanks to you, scientists save valuable time and significantly reduce the risk of errors! Data is gradually taking shape and it is finally possible to start interpreting it.

WEEK 3 : Unknown zone mission
Understanding the data
Nautilus Logbook — Day 13 The laboratory screens remained on late into the night. For several days, scientists have been collecting thousands of measurements: temperatures, depths, sonar readings, oxygen levels... Until now, this data mostly formed a vast mosaic difficult to interpret. Today, they are starting to tell a story...
Your turn to play
Complete the sentence by placing the proposed words in the correct position. Each word can only be used once.
Let's go!
Excel's Quick Analysis tool allows quick access to charts, calculations, tables, or conditional formatting with just a few clicks, without navigating through all the Excel menus. It’s an excellent way to quickly explore data, especially when you’re starting out or want to save time.
The initial conclusions are beginning to emerge from the analyses... Some areas appear richer in resources, others display particular characteristics that warrant further attention. Gradually, the mapping of depths becomes more precise.

WEEK 3 : Unknown zone mission
Choose the right tool
Not all problems are solved in the same way. Some situations require calculations, others quick searches, sorting or comparisons. In the laboratory, teams have many tools at their disposal, but you need to know which one to use depending on the need encountered...
You think you master the features, but will you be able to make the right choice in a real situation? Only one answer is correct and the others might make you hesitate...
Pivot Tables allow you to summarise, analyse and explore your data interactively. However, Sparkline charts and Segments enable you to visualise trends and filter data, but they are not sufficient for analysing or synthesising it.
Congratulations, the work is progressing faster and the analyses are becoming more reliable. Meanwhile, the navigator is gradually gathering all the discoveries made since the start to prepare a comprehensive summary for the crew.

WEEK 3 : Unknown zone mission
Highlighting the essentials
Faced with hundreds of reports accumulated over several weeks, scientists are now looking to highlight important data at a glance. Critical levels, anomalies, equipment to monitor, remarkable resources... Some information clearly deserves to attract attention before others.
Did you know that it is possible to improve data readability through conditional formatting? Observe this table without formatting: it is difficult for the crew to quickly identify important information or areas requiring special attention.
Answer the following questions to gradually reveal the conditional formatting and discover how it helps make a table clearer and easier to analyse.

New week on board completed! Your valuable help allowed essential information to appear immediately and the crew to make decisions more calmly. On his side, the captain is finalising preparations for the next stage. The Nautilus is about to enter an unknown zone...
See you next week to prepare for this new stage!
Le port n'est plus qu'un souvenir lointain. Autour du Nautilus, les profondeurs deviennent plus sombres et plus mystérieuses à mesure que l'expédition progresse.
À bord pourtant, le calme des abysses contraste avec l'agitation qui règne sur les écrans : messages, alertes et rapports se multiplient.
Et lorsqu'une information importante se perd dans le flot des communications, c'est toute l'expédition qui risque de perdre sa route.
Cette semaine, le capitaine compte sur toi pour remettre de l'ordre dans ce flot de communications avant qu'il ne ralentisse la mission.
