Excel Power Query refresh suddenly incredibly slow

Our take

Hi everyone, I’m facing an issue with a Power Query refresh in Excel that has suddenly become incredibly slow. Despite refreshing this file daily and making no significant changes—just altering data types—the refresh time has ballooned from a few seconds to an indefinite wait. The file isn’t large, with around 5,000 lines, and I’ve already tried adjusting privacy levels, background refresh, and fast load options based on online suggestions, but nothing seems to resolve the problem. How can I effectively troubleshoot this? Thank you!

In the dynamic world of data management, users often face unforeseen challenges that can disrupt their workflow. A recent post on a community forum highlights a particularly frustrating issue: a user’s Excel Power Query refresh has suddenly slowed to a crawl, despite no changes to the file or its source. This scenario is not just an isolated incident; it reflects a broader concern that many professionals encounter as they navigate the complexities of traditional spreadsheet tools. For instance, similar discussions about slow spreadsheet performance can be found in articles like Slow spreadsheet - need troubleshooting, where users seek solutions for performance issues stemming from various sources.

The user, known as /u/Loose_Biscotti9075, describes a situation where a daily routine has been disrupted, which can have significant implications for productivity. Even a minor delay in data refresh can ripple through an organization’s operations, causing delays in decision-making and insights. This scenario underscores a critical point: while spreadsheets are powerful tools for data management, they are not immune to performance issues. Such slowdowns can be particularly frustrating when users have invested time in optimizing their workflows, only to see them hindered by factors that may seem beyond their control.

In the case presented, the user has already attempted several troubleshooting steps, such as adjusting privacy levels and enabling background refresh. However, these measures have not yielded any improvements. This situation raises an important question: how can users effectively address performance issues in their spreadsheets? The answer lies in understanding the underlying technology and incorporating innovative solutions that can enhance performance. Users might consider exploring alternative data management tools designed to handle larger datasets or more complex queries more efficiently. For example, embracing AI-native spreadsheet technologies can simplify the process of data manipulation, allowing users to focus on insights rather than technical hurdles.

Moreover, this discussion highlights a broader trend in data management—the need for tools that not only deliver results but also adapt to user needs. As organizations increasingly rely on data-driven decision-making, the demand for solutions that prioritize speed and accessibility will only grow. It is essential for users to remain open to exploring transformative solutions that can streamline their workflows and empower them to harness the full potential of their data. This aligns with the evolving landscape of data management, where traditional tools may no longer suffice in meeting modern demands.

As we look to the future, the challenge presented by slow spreadsheet performance serves as a reminder of the importance of adaptability in a rapidly changing digital environment. Users must not only address immediate concerns but also embrace a mindset of continuous improvement and exploration. The key question for many will be: how can we leverage innovative technologies to enhance our data management processes and ensure we remain productive in an increasingly data-driven world? By staying informed and proactive, users can continue to transform their workflows, turning challenges into opportunities for growth and efficiency.

Hi everyone,
I have a file that I refresh daily with several queries.
One of those became incredibly slow (few seconds to hasn't finished yet) from one day to the next. Nothing changed in the file or source, it is not very large (~5000 lines) and without any manipulations other than changing the data type.

I have tried to change the privacy levels, background refresh, fast load and so on as I found online, but nothing helped. How can I solve this?

Thank you!
