PowerQuery takes an extremely long time to load intermediary steps.
Our take
Power Query (PQ) has become a vital tool for data manipulation and transformation in various industries, enabling users to connect, combine, and refine data from multiple sources effortlessly. However, as highlighted by a recent query on Reddit, even seasoned users can encounter frustrating performance issues, particularly when dealing with intermediary steps during the refresh process. The concern raised—why intermediary tables can take longer than the overall refresh time—is not just a technical hiccup; it reflects deeper implications about user experience, productivity, and the limitations of current tools.
The user’s experience of waiting over five minutes to load intermediary steps serves as a reminder of the complexities inherent in data management. This situation illustrates a common challenge faced by many data professionals: the balance between the richness of insights derived from detailed data transformations and the efficiency of the tools used to achieve them. The time taken to refresh and view intermediary steps can significantly impact workflow, leading to frustration and decreased productivity. This resonates with other discussions in our community, such as those found in articles like Conditional Formatting for Dates within 30 days or past due- needs to account for the year! and First-occurrence tracking with SCAN & LAMBDA (And how to fix the blank row bug), where users seek more efficient solutions to common challenges in their data processes.
Understanding the root causes of delays in Power Query is crucial for optimizing user experiences. Factors such as data volume, complexity of transformations, and network speed can all contribute to slow loading times. Moreover, the design of Power Query itself may lead users to inadvertently create complex dependencies that exacerbate these issues. For example, a user might add multiple transformation steps without realizing how each one compounds the overall load time. This underscores the importance of not only using powerful tools like Power Query but also developing a strategic approach to data transformation that prioritizes efficiency.
As we look toward the future of data management, it’s essential to acknowledge that while tools like Power Query provide powerful capabilities, they also require users to adapt their workflows and strategies accordingly. The challenges highlighted in this discussion raise important questions about how we can improve our data processes. Are there best practices that can be adopted to minimize refresh times? How can innovations in AI and machine learning further enhance our data transformation capabilities?
In conclusion, the ongoing dialogue around Power Query performance is a microcosm of the broader evolution in data management technologies. As the landscape continues to change, users must remain proactive in exploring new strategies and tools that can streamline their workflows. The question moving forward is not only how to address current limitations but also how to empower users to fully harness the potential of advanced data technologies in their everyday tasks. As we navigate these changes, the focus should remain on enhancing user outcomes and fostering an environment where data can be managed efficiently and effectively.
I have a PQ that I use regularly that takes about 5 minutes to refresh from start to finish. Recently I’ve been doing some development/ bug fixing and when trying to look at some of intermediary steps, the tables are taking >5 minutes to load. What could be the cause of this?

- Power Query Refresh TimeI created an Excel file with a Power Query product database. It takes item-level data (sizes, colors, logos, etc.) from an Item Master, expands it into all SKU combinations, and builds out a final product database with pricing and item info. It also pulls in a predetermined product codes from a separate tab with 300,000 rows. When I refresh the file (both at home and at work), it takes about 20 seconds with 50 rows. I had a couple coworkers try the exact same file, and it takes about 2 minutes for them to refresh. It is the same file, same data, same network, and similar computers. I can’t figure out why it’s consistently faster for me than everyone else. Any ideas of what could be causing this? submitted by /u/Presto1985 [link] [comments]
- PowerQuery hangs forever in refresh when multiple computers are used to editI'm having a sudden problem in which when I make edits on another computer and try to refresh PowerQuery on my primary computer, it refreshes forever or sometimes refreshes for hours before throwing up a random memory error. Normally, the refreshes take between 3 and 10 minutes. I've used this setup for a year now with no issues before last week. I have an relatively elaborate PowerQuery setup that pulls in shared data from many sources, including online, Dropbox, SharePoint, OneDrive, and in-workbook excel tables. Lots of merges, lots of custom formulas. All file locations are variable parameters that are changed via a dropdown in Excel. I do most of my work on an up-to-date Windows 11 version of Excel running on a Mac via Parallels. The other machine I occasionally edit on is another up-to-date version of Excel on Windows 11. They are synced via Dropbox. At first I thought my VM was corrupted, so I reinstalled fresh. It worked fine until the next time I edited on another machine. I've deleted all PowerQuery and Excel caches and it still happens. Nothing I'm doing is new, so I'm not sure why it suddenly breaks. Any thoughts? submitted by /u/WorldsGreatestWorst [link] [comments]
- Excel Power Query refresh suddenly incredibly slowHi 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! submitted by /u/Loose_Biscotti9075 [link] [comments]
- Power Query refresh speed with multiple usersHello all. I have a report that has multiple queries with data sources saved in SharePoint. Enable Fast Data load is checked in all the queries. There are about 10 users, with reported run time of around 5-10 minutes. But for me and one user, it takes 30-60 minutes to finish refreshing. I have already made some improvements in the initial code, and did a clean up of old raw data files in SharePoint but this resulted to minimal improvements. Given that all users have the same laptop configurations and are connected to the same internet connection, what are some steps I can do to do improve the speed on the queries? submitted by /u/SYSTEMOFADAMN [link] [comments]
