Power Query - How to merge multiple sheets through common ID without invoking them in separate files?
Our take
The challenges of data management in Excel, particularly with Power Query, resonate with many users who navigate complex spreadsheets daily. In the article discussing how to merge multiple sheets through a common ID without invoking them in separate files, the author highlights a common frustration: inconsistencies in data organization that hinder effective analysis. This situation is not isolated; many users face similar dilemmas, especially when dealing with automated outputs from machines. As the need for streamlined data processes grows, it’s crucial to explore innovative methods that enhance productivity. Readers facing parallel issues may find value in similar discussions about navigating Excel’s limitations, such as in Is there are any alternatives for macabacus on mac? or How to remove this copilot thing ?.
The author’s predicament illustrates a broader challenge in data management: ensuring that information is both accessible and actionable despite its inherent complexity. The need to merge data from multiple sheets, especially when they contain varying information formats and column names, can feel overwhelming. Here, Power Query offers a powerful solution, yet the limitations faced—such as the inability to merge sheets when column names differ—underscore the necessity for a more adaptable approach. The struggle to maintain data integrity while navigating these obstacles speaks to the evolving demands of users who seek not just to store data but to derive meaningful insights from it.
Moreover, the specific issues raised about the varying order of file names and the presence of incomplete data on different sheets highlight a critical point: data management is not just about the tools used, but also about how effectively those tools can be adapted to meet user needs. The author’s experience reflects a significant trend wherein traditional spreadsheet methods begin to fall short, especially for users who rely on automation and streamlined processes. This calls for a re-evaluation of how we approach data integration, suggesting that embracing tools that offer more flexibility could significantly enhance workflow efficiency.
As we look toward the future of data management, it becomes evident that the landscape will continue to evolve. Users are increasingly seeking solutions that allow them to overcome the limitations of legacy systems while leveraging new technologies that promote ease of use and accessibility. The question remains: how can we bridge the gap between complex data requirements and the tools available? As we explore further, it will be essential to monitor the development of innovative solutions that not only simplify processes but also empower users to take control of their data management strategies. In this rapidly changing environment, those who adapt and innovate will undoubtedly lead the way in transforming how we interact with data.
I made a post previously but I omited too much so I could not make use of help, my apologies.
I have a machine which outputs excel file with information stored in following manner:
* n number of sheets with information about specific material per property (varies between 2-4 so far), with first sheet always being useless to me (always called "Details")
within the sheet:
* row with sheet name
* row of column names
* row of units (accidentally omitted)
* data (majority omited for lack of need)
Each sheet column names are almost the same but carry differnet information (e.g. "Enthalpy" or "Peak Temperature" are not the same; "File Name" and "Name" are the only true same between the sheets.)
Problem I encountered is that sometimes the machine outputs file names in different order between sheets, and occasionally I will have information only on one of the sheets.
All as shown below.
For when they were in correct order I used the script below.
I want to edit it to account for those misplacements, which cannot be through formula in native excel because I pull it into different excel file. I tried doing so through table.combine (no can, merges false same columns), and through Table.NestedJoin (can only merge one by one, which is both a hustle and if I change the number of sheets in the future it will break).
Is there a way to append any number of all of them at once through file name only?
Source = ...
#"Filtered table" = Table.ReplaceValue(Source, each [Data], each Table.Skip(Table.PromoteHeaders(Table.Skip([Data],1)),1), Replacer.ReplaceValue, {"Data"}),
#"Filtered Rows" = Table.SelectRows(#"Filtered table", each [Name] <> "Details"),
pref = Table.CombineColumns( #"Filtered Rows" , {"Name", "Data"}, (x) => Table.ToColumns(Table.DemoteHeaders( Table.PrefixColumns(x{1}, x{0}))), "data"),
#"Change headers"= Table.PromoteHeaders( Table.FromColumns(List.Combine(pref[data]) )),
#"Removed Other Columns" = Table.SelectColumns(#"Change headers",{"Glass transition.File Name", "Glass transition.Midpoint", "Hc.Enthalpy (normalized)", "Hc.Peak temperature", "Peak Integration (enthalpy).Enthalpy (normalized)", "Peak Integration (enthalpy).Peak temperature"}),
#"Split Column by Delimiter" = Table.SplitColumn(#"Removed Other Columns", "Glass transition.File Name", Splitter.SplitTextByEachDelimiter({"_"}, QuoteStyle.Csv, true), {"Material", "Run"}),
in
#"Split Column by Delimiter"

- Power Query Help Merging Spreadsheets with Compound HeadersI've been using Power Query to combine tables from multiple workbooks. It's fairly straightforward when every worksheet has exactly the same headers in exactly the same order in the top row. However, I'm trying to merge many different spreadsheets which have "compound headers," meaning each column's unique identifier is the top 4 rows. (Row 1 is the result type, Row 2 is the Cycle Number, Row 3 is the Analyte Name, and Row 4 is the Unit.) To complicate things even more, not every spreadsheet contains data for all the same headers, because sometimes we don't test all the same chemicals, and sometimes we don't test in the same units. See an example of just 4 of the worksheets I'm working with here: https://drive.google.com/drive/folders/1iZpvy7OSmltpduB0DdGKoGRTysHXHu_j?usp=sharing I've deleted all the actual data and replaced it with a blue block, but you can see the layout. I'd like to preserve all the data in the resulting merge. In other words, I don't want to only keep columns that exist in every spreadsheet. I want to keep all columns that appear at least once. The end goal is to be able to filter the table to find all the samples named "CCV" or "RLV" for example and trend their respective data. (We don't always include the data in the sample name in Column B, so adding a column for the source file name would be necessary as well, so that we know which date the data is for.) Please let me know how I might do this with Power Query, or if there's a better way. We have dozens of these files, and we'd really like to avoid copying and pasting all day. Thanks so much for the help. submitted by /u/7Xe3V7Ur [link] [comments]
- Power Query - is there a way to combine columns from separate sheets so that rows with the same "name" in a specifed columns always match?Hi. I am working with a software which exports to values which refer to the same object into separate sheets (e.g. melting and boiling point), but sometimes it does not add correctly so, e.g. in ref1 sheet thing b is in a second row, but in data sheet b is in 3rd row. Is there way in PQ to combine columns so that it first matches the text in "Name" (they are always in the same column) and then combines rows correctly? There are, however, cases where there is a name in first sheet but there is no match for it in the second sheet https://preview.redd.it/ni9mpe0kkh3h1.png?width=700&format=png&auto=webp&s=e5418166f2cfcb6cc74c9efee264e27727117dc4 submitted by /u/3and12characters [link] [comments]
- How to link data from specific columns on one sheet to another, then sort it column A alphabetically and match the other columns based on corresponding data from Sheet 1I am a beginner at attempting to write formulas in Excel, and I am currently using Excel on a web browser mainly but can and do occasionally edit in the desktop version. I believe the version is Microsoft Office LTSC Professional Plus 2024 in the desktop version, or at least that's the product activated. I have two sheets on the same spreadsheet, and I want to pull in the data from 4 different columns to the second sheet and have it automatically update when there are changes or additions to the first sheet. I have a couple issues making this happen - the main one is that the data in my first sheet is custom sorted by color, but I want the new sheet to take the data from column B on sheet 1 and sort it alphabetically, and take the other columns and match them correspondingly to the correct values they match to from column B on the first sheet. Secondly, for blank cells, I want it to leave them blank instead of inputting zero, or any dates. I don't know if this is all even possible, or if I should just remove my custom filters from sheet 1 by cell color and just link it that way. I've spent hours trying to find formulas that work. Please see attached images for reference on what I've tried, and for more clarification as to exactly what I'm requesting. Sorry for the copious redacting, I wanted to be safe rather than sorry with identifiable info regarding this. Any help would be greatly appreciated. https://preview.redd.it/6vt2ocasj9kg1.png?width=1199&format=png&auto=webp&s=35a78bf5c6d96437094c04023d3ca24fa6ec3399 https://preview.redd.it/kqbi5za5k9kg1.png?width=791&format=png&auto=webp&s=f80ee9272131546132c6925e5d0a8b9dc3ae74f2 https://preview.redd.it/1947drz7k9kg1.png?width=836&format=png&auto=webp&s=4c07c1354c348ee85b1a556d21dd0c677b1ae659 https://preview.redd.it/8ynxkp39k9kg1.png?width=869&format=png&auto=webp&s=7d69705a4a61702e0f89a49f485f8cf53d230146 https://preview.redd.it/7fd5p2v9k9kg1.png?width=943&format=png&auto=webp&s=cd3c9fe721db57b44f7b5260ac891641a80170a0 submitted by /u/MeretrixRex [link] [comments]
- Power query multiple workbooks and sheetsI am trying to combine multiple workbooks that have multiple sheets but I am missing a step. Get data, from file, from folder and open. Transform. Add custom column (=Excel.Workbook([Content]). I select data, item and kind from the custom drop down. Then I filter item to select the specific sheets I want. Close and load. When I do this, I only get the filepaths of the sheets I selected. I tried the same steps, but I clicked on the "Table" link in the custom data column before close and load. It brings up the data for that worksheet and it's correct. But when I then close and load, it will bring up the actual data, but only for that worksheet that I looked at. How do I get the *data* from all the worksheets that I selected in custom data to load. Or am I completely off base? Thanks! This is my first foray into power query and it's a bit daunting. submitted by /u/Choice_Intention_778 [link] [comments]
