Power BI Style Presets: Simplify Template Design with JSON

Key insights

• Style Presets in Power BI let users quickly change the appearance of visuals with one click, making it easy to update tables, matrices, and other elements for a consistent look.


• JSON Themes allow for advanced customization by letting users define color palettes and styles in a JSON file, which can then be imported into Power BI to apply uniform formatting across reports.


• Consistency is improved because both style presets and JSON themes help keep all reports visually similar, supporting professional branding and presentation standards.


• Efficiency increases as applying a preset or theme saves time compared to changing each visual’s format manually, especially when working on large or multiple reports.


• Implementation: Users can select built-in style presets from the Power BI interface or create custom ones by editing default settings. For JSON themes, users write their desired styles in a JSON file and import it into Power BI Desktop for use.


• New Developments: Recent updates now allow style presets on more types of visuals beyond tables and matrices. Enhanced validation tools make creating complex JSON themes easier and more reliable for all report elements.

Introduction: Exploring Power BI Style Presets Through Fernan Espejo’s Tutorial

In the dynamic world of data visualization, maintaining a consistent and professional appearance across reports is essential. Recently, a detailed you_tube_video from Fernan Espejo, the creator behind Solutions Abroad, has captured the attention of Power BI enthusiasts. This tutorial, entitled “Set Up STYLE PRESETS THE EASY WAY // Power BI Template Styles using JSON,” guides viewers through the process of efficiently implementing style presets and JSON-based themes within Power BI. While Fernan Espejo is not the author of this article, his expertise and practical approach offer valuable insights that merit a closer look. By summarizing and analyzing the key points raised in his video, this article aims to inform readers about the advantages, tradeoffs, and challenges associated with leveraging these customization tools in Power BI.

The Basics: What Are Style Presets and JSON Themes in Power BI?

To begin with, understanding the foundational concepts is crucial. Power BI’s style presets allow users to quickly change the appearance of visuals, such as tables and matrices, with just a few clicks. This means that instead of manually formatting each visual element, users can apply a preset style across multiple objects, ensuring a uniform and polished look. Transitioning to a deeper level of customization, JSON themes empower users to define comprehensive color palettes, text formatting, and even intricate visual object styles. By creating a JSON file, users can specify how every aspect of their report should appear, from background colors to font types. Once this theme is imported into Power BI Desktop, it can be applied to any report, making it easier to maintain branding and visual consistency across multiple projects. Furthermore, the video demonstrates how to implement these features step by step. For style presets, users simply select from predefined options within Power BI. Meanwhile, for JSON themes, the process involves crafting a JSON document with all desired styling parameters and then importing it into the platform. This approach not only saves time but also reduces the likelihood of human error during manual formatting. However, the initial learning curve for writing JSON files can be a challenge, especially for those new to coding or data visualization tools.

Benefits and Tradeoffs: Consistency Versus Flexibility

One of the central messages in Fernan Espejo’s video is the balance between consistency and flexibility when using style presets and JSON themes. On one hand, these tools greatly enhance consistency across reports, which is vital for organizations committed to strong branding and professional communication. When every report adheres to the same color schemes, fonts, and layout styles, stakeholders can quickly recognize and trust the information presented. On the other hand, the pursuit of uniformity can sometimes limit creative flexibility. While style presets and JSON themes cover most formatting needs, they may not always accommodate unique design requirements for specific projects. For instance, a report intended for a special campaign might demand a distinct look that deviates from the standard theme. In such cases, users must weigh the benefits of consistency against the need for customization. Additionally, developing and maintaining complex JSON themes requires both technical skill and ongoing effort, particularly as Power BI updates introduce new features or visual types. Another tradeoff involves efficiency. Applying a style preset or a JSON theme is undoubtedly faster than manual formatting. Yet, building and refining the initial theme can be time-consuming, especially for beginners. Organizations must decide whether the upfront investment in learning and configuring these tools will pay off in the long run through streamlined report creation and reduced formatting errors.

Recent Developments: Evolving Features and Improved Usability

The landscape of Power BI customization has evolved significantly, as highlighted in Fernan Espejo’s tutorial. Recent updates have expanded the range of visuals that support style presets, moving beyond tables and matrices to include a wider array of chart types. This advancement enables report creators to apply cohesive styles to more complex dashboards, further enhancing the user experience. Moreover, improvements in JSON theme validation and documentation have made it easier for both novice and experienced users to craft robust themes. Power BI now offers clearer error messages and more detailed guidance, reducing frustration and increasing adoption rates. These developments lower the barrier to entry and empower more users to take advantage of advanced customization options. However, challenges remain. As new features are introduced, existing themes may require updates to remain compatible. Users must stay informed about changes in Power BI’s capabilities and best practices to ensure their themes continue to function as intended. This ongoing maintenance can be demanding, particularly for organizations with limited technical resources.

Practical Implementation: Step-by-Step Guidance and Real-World Use Cases

Fernan Espejo’s educational approach shines in his practical demonstrations. He walks viewers through creating a sample JSON file, utilizing theme generators, and copying templates for reuse. These step-by-step instructions demystify the process and make the tools accessible, even for those with minimal programming background. Additionally, the video includes examples of useful presets that cater to different reporting scenarios. By showcasing how style presets can be applied to various visuals, Fernan illustrates the versatility and adaptability of these tools. He emphasizes the importance of starting with simple themes and gradually incorporating more advanced features as users become comfortable with the technology. In real-world settings, teams often face tight deadlines and shifting requirements. The ability to quickly adapt report styles without redoing all formatting work provides a clear advantage. Nevertheless, organizations must also invest in training and knowledge sharing to maximize the benefits of style presets and JSON themes. Without proper onboarding, the potential for inconsistent application or underutilization increases.

Conclusion: Future Prospects and Ongoing Challenges

In summary, the use of style presets and JSON themes in Power BI, as explained by Fernan Espejo, offers a powerful means of enhancing report customization and ensuring visual consistency. These tools streamline workflows, reduce errors, and support organizational branding efforts. Yet, they also introduce tradeoffs between consistency and flexibility, as well as challenges related to initial setup and ongoing maintenance. As Power BI continues to evolve, users can expect further enhancements in customization features and user support. Staying informed about updates and best practices will be essential for organizations seeking to maintain a competitive edge in data visualization. Ultimately, the path to effective report design lies in balancing the efficiency of standardized styles with the adaptability required for unique business needs. By leveraging the guidance provided by experts like Fernan Espejo, Power BI users can confidently navigate the complexities of style presets and JSON themes, unlocking new levels of professionalism and impact in their reporting efforts.
