3 cas d'usage réels de Claude Code en 2026 (Débutant)

Today, I will demonstrate three examples of Cloud Code's utility, challenging the common misconception that it's exclusively for developers. My name is Shubam Sharma, and with a background as a development engineer in various French startups, I now assist companies with these types of subjects. I will show you how Cloud Code, a powerful tool, can significantly aid your daily tasks through practical examples. We'll start with the first example: analyzing Excel files. I have an Excel file here, a sort of construction plan, which I find completely unreadable. While Excel enthusiasts might argue that numerous visualizations can be created, Cloud Code offers a superior and more advanced approach. To achieve this, we first open Cloud, which presents the classic Cloud AI interface on your computer. To access Cloud Code, you click a specific button that leads you to a different facet of Cloud. Unlike Cloud, which functions as a chatbot for discussions, Cloud Code allows you to write various files, including HTML files, directly on your computer. As you can see, I've used Cloud Code extensively recently, with 502 sessions and 60 active days. I rely solely on it because, unlike Cloud, where you interact with its AI, Cloud Code enables file creation, modification, and script generation on your computer, performing many actions on your behalf. To do this, you must first grant it access to a specific folder. I'll select "folder 1," which contains the construction Excel file I just showed you. Once selected, I can chat with Cloud Code, and it will perform tasks for me. For instance, I'll ask it a simple request: "I have a complete construction Excel file. Create an interactive, single-page HTML infographic that visually explains where my money goes." After entering the prompt, I can choose different models. If you're new to Cloud Code, you might encounter a prompt to activate permissions. I recommend setting it to "activate modifications" so it can directly interact with your computer. You can authorize each modification individually, but with frequent use, this becomes repetitive. Therefore, I now set it to "ignore permissions." Be cautious, as this can be dangerous for beginners, so initially, accept permissions one by one. Once you understand the process, you can switch to ignoring permissions. The first step Cloud Code undertakes is analyzing my Excel file, reading its various tabs, and then generating a visualization dashboard. It confirms it has processed all the details and is now building the infographic with the available data. The creation process is now complete, and the infographic has been generated. Cloud Code has a built-in browser, but I find it impractical. So, I'll copy the path or display it in Finder, then double-click to open it in my preferred browser, like Google Chrome. The result is an interactive infographic that provides a better understanding of my Excel file's contents. It includes details on specific sections, as my Excel file also contained a summary definition, which Cloud Code successfully read because the file was on my computer. It provided a recap with milestones, a payment schedule, and VAT vs. ex-tax breakdowns. Next, let's explore how to analyze bank statements. I have a bank statement for 2024. While there are applications for analyzing such data, they usually rely on bank synchronization, not direct statement analysis. I want to analyze this specific statement. It's stored in a folder. I'll launch Cloud Code, switch to the correct folder (e.g., "bank"), which contains my statement file. Then, I'll instruct it: "I have this bank statement for the entire year 2024. Analyze it and create an HTML page. Categorize expenses, identify major spending areas, show yearly evolution, and help me understand my budget at a glance." Unlike the standard Cloud, Cloud Code can write files directly to my hard drive, so it will generate the HTML file for this analysis. You might argue that Cloud can also do this using "artifacts" for file visualization. However, with Cloud Code, you have greater control over the files. I'll wait for it to read the file, ignoring permissions. If I want to modify the style, connect it to other data sources, or export data to Google Sheets, Cloud Code makes it much easier. It has now read all 24 pages and is creating the HTML analysis page with total expenses per category. The output provides a budget analysis, including a pie chart and automatic categorization of transactions. It also shows month-by-month evolution, generating a comprehensive file. With Cloud Code, I can make more modifications and connect it to external sources, unlike the standard Cloud. As a non-developer, I'll stick to this example, but the possibilities extend much further. If I have an HTML file, I can simply ask Cloud Code to "Convert this file to PDF so I can send it by email." It will then convert it to PDF. It achieves this by utilizing a built-in skill, possibly by leveraging Chrome, making it more autonomous than Cloud. Moving to the next example, I have a PDF document—a non-furnished rental agreement, a lease. These administrative documents are often tedious to fill out, but Cloud Code can handle them. I'll use Cloud Code to write onto and modify this PDF. I'll start a new session, select the correct folder ("rental agreement"), where "input" is the PDF I showed you. I'll then instruct it: "Fill this file with invented fictitious information. I want the fields to be filled correctly and cleanly, without overflow." First, it will analyze the file. My file has fillable fields, which isn't always the case, but Cloud Code can still manage even if it doesn't. Second, it will invent data and write it onto the file. This process takes a moment. I'll authorize it, and then set it to "ignore permissions" for future convenience. The result is a new file named "output.pdf." When opened, it reveals that Cloud Code has filled in all the editable fields with invented information, saving a significant amount of time for anyone working with PDFs. In a similar vein, I have a CERFA form, a vehicle transfer certificate, with slightly more complex fields. I'll ask Cloud Code to fill these as well. In a new session, I'll change the folder to "CERFA," which contains the file. My prompt will be: "Fill this file with invented fictitious information. I want it simply and cleanly, without overflow. This is a CERFA, so correctly fill in the SIRET number and add a signature." Adding a signature is something it hasn't done before. A brief note: Cloud Code is only available with a Pro plan, so it's not accessible on the free tier. I'm using Opus 4.7, which is considered the most intelligent Cloud model. However, for tasks like this, Sonet 4.6 or Haiku often work well. Opus 4.7 is generally reserved for more complex, reflective tasks. I have a Max plan, so I rarely run out of tokens and use Opus 4.7 for speed and a one-shot result. The result is impressive: it filled in the information, including dashes, and even added signatures. It's remarkable how it handled this document in one go, especially with Opus 4.7, as such documents often pose challenges. While signatures can typically be added using Preview, this demonstrates Cloud Code's capability. We've seen how to write HTML and PDF files, and also how to fill PDFs, which can be a huge time-saver. You can test it with any file type; if there are no editable fields, it often takes screenshots and writes over them. I encourage you to try it for your next administrative task. For the final part of this video, we'll look at generating slides with Cloud Code, one of my most frequent uses. Creating slides is time-consuming, especially for someone who pays attention to detail, so I let Cloud Code handle it. For instance, I have meeting minutes in a Word document. I'll ask Cloud Code to read this document and then create a slide presentation from it. Previously, I often used Gamma for such tasks, but I found the results to be subpar. The images often looked like AI-generated art, the presentation quality was poor, and it became obvious that Gamma was used. Now, with Cloud Code, I'll select the correct folder ("meeting minutes") and provide the prompt: "Transform this executive committee meeting report into a beautiful, interactive HTML presentation for the board of directors. It's for 'À quoi rêve'." You'll see the quality of the presentation it generates, even with this minimal prompt. I performed the exact same task on Gamma, and here's the result: I gave Gamma the same meeting minutes content, and personally, I don't find the outcome impressive. Moreover, it's becoming increasingly obvious when AI is used in presentations, especially in companies where AI adoption is growing. Now, let's see what Cloud Code produces. The result is significantly better, and I can further enhance it using various "skills" available on Cloud Code. One skill I frequently use is called "Impeccable," which improves the rendering quality of applications and other outputs. If you're interested, I've linked all my frequently used skills in the description. Many other sites offer skills, but I find there's a difference between those advertised online and those that are truly useful. So, feel free to check the link. I constantly create slides with Cloud Code. The quality it can achieve has improved dramatically in recent days, and it's incredibly fast. I find Cloud Design produces even better results, to the point where my last example might soon become obsolete. I urge you to try Cloud Design, which was released a few days ago. I even made an Instagram Reel this morning explaining how much it has impacted Figma, another design tool company. Cloud Code is effectively replacing Figma. If you'd like a video on that topic, please let me know in the comments. In any case, I encourage you to download my skills to delve deeper into Cloud Code, or watch this video, which explains how to use Cloud Cowork, another way to leverage Cloud. See you soon!
