Filter only most recent value in each day from a query
Our take
In the realm of data management, particularly with tools like Power Query, users often encounter challenges that stem from the complexity of data sources. A recent query concerning the extraction of the latest exchange rates exemplifies this issue. The user, seeking to streamline their data process, is overwhelmed by multiple daily entries for currency exchange rates, ultimately requiring only the most recent value for each day. This scenario underscores a common frustration among users who rely on frequent data updates but wish to maintain simplicity and efficiency in their workflows. As seen in related discussions like Power Query - select latest file and Power Query: my source doesn't always contain the same columns. How do you handle this?, the intricacies of managing dynamic datasets can quickly become cumbersome, especially when facing inconsistent data formats.
The user’s preference for resolving this issue within Power Query, rather than resorting to external solutions like downloading CSV files manually, highlights a critical aspect of modern data management: the need for tools that facilitate seamless integration and automation. Manual interventions, such as downloading and formatting data, not only consume time but also introduce the risk of errors, which can ripple through to the final analysis. This situation serves as a reminder that the true power of spreadsheet technology lies in its ability to automate and simplify data handling processes. By harnessing the capabilities of Power Query effectively, users can eliminate unnecessary steps, ensuring that their data is not only accurate but also readily accessible in its most useful form.
Moreover, the reliance on outdated methods—like manual downloads and adjustments—points to a broader trend where legacy tools and practices impede productivity. As users increasingly seek innovative solutions, it becomes imperative for spreadsheet technologies to evolve. The current landscape necessitates a shift towards more intuitive, user-centric approaches that prioritize the end-user experience. This is not just about keeping pace with technological advancements; it’s about fostering an environment where users feel empowered to explore and utilize data without fear of complexity or inefficiency.
As we look to the future of data management, the focus must remain on creating solutions that are not only powerful but also accessible. The challenge lies in balancing the sophisticated capabilities of tools like Power Query with the user-friendly design that demystifies complex processes. Readers should be aware of the ongoing developments in spreadsheet technology that aim to simplify these tasks. With advancements in AI and machine learning, we are likely to see even more intuitive features that help users navigate their data effortlessly.
Ultimately, the question we should be asking ourselves is: How can we further enhance the user experience in data management to ensure that technology serves as an ally rather than a hindrance? As we continue to refine our approaches and tools, the goal should be to empower users to discover, explore, and transform their data with confidence and ease.
I have a query that pulls exchange rates. Unfortunately the data available contains all of the daily currency exchange rate reports (4 or 5 per day) but I only need the latest one for each day. Snapshot below shows column with Date and Time (dd/mm/yyyy HH:MM:SS) and the exchange rate. For example, for 02/01/2020 I only want to keep the latest value, from time 13:11:11.
Notice that this is in PowerQuery, and I would rather resolve it here, since I pull this query into different spreadsheets. Maybe a Pivot Table and filter could do it in a table, but then I can't make a query into that PivotTable.
My current workaround is to download a CSV from another source, but I have to manually download it and manually replace colons, commas etc. to match the desired format.
STOCKHISTORY won't do it, because (a) it's not the official rate, and (b) because the query and the CSV download are alway automatically updated to the latest date.
Thanks for any suggestions.

- Power Query - select latest fileHi! I’m grappling with the following structure: Twice per day, at 7:30 and at 14:00, an exported csv file is added to a sharepoint folder. The csv shows a snapshot of the current state of system data, so there’s no need for all of the csvs to be ingested. I need to always ingest the latest file. The naming convention is “export yyyy-mm-dd hh-mm-ss”. I tried using sharepoint folder as my connector, navigating to the specific subfolder, sort by date added, keep only top row. So far so good, but the next step in the query hardcodes the file name. The next version of the file will have a different timestamp, so the hardcoded name doesn’t correspond to the latest file anymore. Any other approach come to mind? submitted by /u/rumboss123 [link] [comments]
- Power Query: my source doesn't always contain the same columns. How do you handle this?Hi all. I'm producing reporting based on data from our CRM. They're using Looker. My issue is, Looker seems to only generate a field if there's data for it. So my data can include a field on one period, but it might not be present on the next - let's say if no items for Smartphones category are sold, the csv won't have a smartphones column. What's the best way to handle this so that I don't have to spend time every refresh to fix the queries? submitted by /u/m4492 [link] [comments]
