We use Get and Transform Data to create a 3rd and final table from this temporary table and name this new table History_Worksheet. The second is just a temporary table that we are going to use to generate some suitable power query code.Īt Step 4. We now have two Excel tables with the same data. I use the Table Tools tab to name my new table “Table_prices”.Īt Steps 2 and 3, I create a new Excel table with this data. This will get our data and create a table in Excel with a key column. I welcome both praise and comments below – JBĪt Step 1 we are using the “Get and Transform Data” menu. Common tasks include adding additional keys for use in VLOOKUPs and removing blank or duplicate rows. You can now tweak both queries to get the correct columns. The worksheet temp is no longer required and should be deleted. Each time we refresh the table additional rows will be added from the current data table.

Now when this code runs it will use the history table as a data source instead of the temp table. We replace “table_temp” in line 2 with the name of our new history table “table_history”. In line 2 it says that the Source for this table is “table_temp” and that this should be combined with the original data query, in my case “Table_prices” (line 4) After the editor opens you click the Advanced Editor option (1) and look at the code (2). Step 6: Hack the query to use the history table instead of tempĮdit the query again.

It will now contain rows from both your original table and your temporary table. Save this query and view your worksheet History_Worksheet.

In my case the data I download is in Table_prices. We will edit it and convert it into an Append query Home > Combine > Append. Step 5: Edit the query to append the current dataĪt the moment this is normal query. Step 4: Create a new query working against this table (this will be our final query)ĭoing this will create a new worksheet which will be our final history table. Rename this table (top right) to “table_temp”. Step 2: Copy these data values into a new tab called “temp” My table is called “Table_prices” (top right). I use one derived from the current data and time as shown below. Use Get and Transform Data on the Data Tab in the normal way. Step 1: Create a table for your current data We cannot achieve this directly but can if we create a temporary table first. A table that appends the current data to itself.A table bound to a query that gets the current data.This problems has been discussed by Dirk Verliefden and Chris Dutch and others on Technet and I have built on their solution. However this does not append data to an existing table. You might think that you could append data, after all there is a query type call append. It is easy to set up an import but unfortunately Excel always overwrites the old data with the current records. It is very common that you want to import data every day and keep it for future reference.

In this article I will show you how to create a history table for imported data. We have seen how we can combine tables and unpivot data ( Excel articles). Table.I have previously written about the powerful ETL (Extract, Transform and Load) functions that are now in Excel Office 365 desktop edition. If I ignore the last optional parameter of the function, then its structure can be described as follows: If, for example, I want to rename the column name of a table with dynamically vaying column names, I can do this in M with the function Table.RenameColumns(). Sometimes you want to use a certain functionality in M and look for the suitable function. A defined list is introduced with an opening curly bracket „ Functions that use lists as input A list is one of those structured values (the others are records and tables) and it is described as „an ordered sequence of values“. In contrast to primitive values, we have so called structured values in M, which are composed of other values, primitive and structured ones. They are primitive in that way, that they are not contructed out of other values. In M there are two kinds of values: primitive and structured values.

This post is part of a series about lists, records and tables in M. Each value type serves specific purposes and this post is intended to give an introduction to lists. The M language has so-called structured values, to which lists, records and tables belong.
