      Hej,

      I Power Query kan man välja att duplicera eller referera fråga (tabell). Vad är egentligen skillnaden?

      Väldigt enkelt uttryckt så kommer ‘Duplicera’ att duplicera koden för frågan medan ‘Referera’ endast hänvisar till resultatet av frågan.

      Duplicera – används vanligtvis när du vill skapa en liknande fråga och du inte vill skriva samma kod. Du kan göra ändringar i den här frågan.

      Referens – betyder att du vill använda den frågan som resulterar i några andra frågor där din ursprungliga fråga förblir som en basfråga. Den kan i sin tur användas i andra frågor för vidare bearbetning.

       

      Detta är inte helt enkelt att förstå, men prova att skapa ett duplikat och en referens i redigeraren och läs denna text igen.

Used me from learnasy’s excels tutorial during my studies as a student and now as an entrepreneur. Is extremely happy with the layout with videos that are super clear and educational. Would really recommend learnasy to everyone regardless of knowledge level as there are courses for everyone!

I am very happy with the course I took at Lernesy (Excel Bas, digital). It was easy to understand with a good division between recorded pedagogical lectures and assignments. Nice that it is always possible to rewind and get examples if there is something you do not understand. The course has helped me a lot in my role as climate strategist at ZeroMission.

Excel Bas:Good, content-rich and pedagogically structured material with representative knowledge controls. Personally, I really like that the videos are short (2-4 minutes) as it will be easy to keep the focus up and immediately get to practice on the material that one has just had to partake of! Has used Excel a lot before, both in service and in his spare time. Despite this, I learned a lot of new commands and got to test functions that in several cases could have optimized my previous projects, both at work and in my free time!

"Pivottabeller fordypning":Svært godt fornøyd med kurset. Passe lengde på hver forelesning (2 min), god pedagogikk, forelesningene er tydelige i sitt innhold. Endel av stoffet i begynnelsen er svært basis, men senere kapitler tar Pivot et klart tyngre steg videre. Mye smånyttige praktiske tips også å ta med seg innimellom her. Foreleser snakker kanskje litt i raskeste laget tidvis (men det går da an å stoppe filmen og tenke seg om litt, evt spole tilbake:). Videre er det ikke alltid sammenheng mellom quizspørsmålene og vedleggene som trengs til disse (så vidt jeg kan skjønne).

Covers all the basics that enable a deeper understanding for more complicated skills. Effective way of learning and the knowledge is easy to apply when you need them for your own projects.

Superbra och pedagogiskt! Hade dessutom missuppfattat när min kurs gick ut så hann inte slutföra den men fick, inom bara ett par minuter, den förlängd.

Riktigt riktigt bra kurser. Läste excelkurs bas efter fem år på KTH och lärde mig otroligt mycket som jag inte hade lärt mig under min skolgång! Kan verkligen varmt rekommendera dessa kurser. Väldigt pedagogiska och effektiva.

Jag kan verkligen rekommendera Learnseys kurser! Grymt bra, väldigt pedagogiskt upplägg med videos man tittar och lyssnar på som går att upprepa vid behov . Sedan avslutas med Quiz eller övning i excel.

Superpedagogiskt och enkelt att navigera i kursinnehållet. Jag tycker särskilt om funktion att kunna favoritmarkera kapitel. Kundservice är väldigt tillgängliga och snabba. De löste tillgång till engelska kurserna såväl som svenska, då mitt Excel är på engelska. Jättenöjd och kan absolut tänka mig att ta fler kurser via Learnesy vid behov!

Overall a good course, with a very easy/basic start for the first half (5-6 modules) before getting into the 'good stuff'.I consider myself an above-average user of MS Excel and the Office Suite and the later modules did cover some topics in an easy-to-follow way.I did encounter several .xlsx-files along the way with assignments who had suffered from lacking translation and some details were clearly wrong in the file compared to the quiz.These were settings and not values, so the main content can still be approved quality-wise.

Online course: Excell Bas (basics)Great introduction to Excell and its tools!This is, I believe, one of the first and most basic courses that Learnesy offers. It introduces topics such as functions and formulas, navigation through the program, hotkeys, IF-formulas and much more. Each module in the course has a few video lessons of a couple of minutes long and ends with a quiz about the lesson. The quizes also includes applying the lesson learnt to a pre-set excel sheet, which made it easy to quickly learn the tool as I got to apply it directly. As the Excel program is built with multiple tools, the basics course was structured appropriately by going through the tools one by one with a subsequent quiz to test the knowledge.Previously I have used Excell throughout my studies, with some basic application such as creating functions, using pivot tables etc. to handle large data sets for assignments in various courses (mainly industrial economics, material handling and international distribution). This made the first lessons fairly easy as I am familiar with the program, but I also learnt something new in most of the first lessons. For instance, when learning about how to format sheets in excell, the lesson also explained how this can be used in large data sets, which put this into perspective how one tool is useful to solve more complex problems.As I had previous experience, especially the first 3 lessons were rather easy. When I did them, it felt a bit "unnecessary" as I already knew these bits. But they are easy and it goes fast to go through, and it probably depends on the experience of the learner. As the course progressed, I learnt more useful tools that I will continue to use from now on. Especially the lesson about IF-functions and search line/column was new to me, and something I believe I will use in my further studies and career.Something I would have like to have when working with the course, is some form of pdf showing an overview of the course before starting. Even though each lesson is labled, I believe it would be easier to get a grip of the entire course with a mindmap before starting the first lesson.To sum up the Excel Bas course:PROS+ Easy to use and understand the lessons+ Explains usages of different tools for further application+ Great content for a basics course with new tips and tricks as well as new knowledge of tools. Well suited for a self-taught learnerPOTENTIAL IMPROVEMENTS- Have a "cheat sheet" with everything learnt from the course to have as a refresher for my self- Include a mindmap of the overview of the course prior to starting the first lesson- Some quizes were a bit too easy, but that may depend on the course and your level of expertise in Excel prior to enrolling in a courseAll in all, a great course to improve my abilities in excel!
