Dynamically Remove Null Columns In Power Query With M Code Lets use drill down or removedothercolumns [column] to convert the table into a list. drill down converts the table into a list of values, i have named this step as columntokeep. Basically if all the entries in a given column is null, the column should be removed. table.columnnames(#"expanded"),each list.nonnullcount(table.column(#"expanded", )) <>0 ), do you have to check whether the entire column is null or can you just check the first row and remove null columns that way.
Dynamically Remove Null Columns In Power Query With M Code Anyway, "remove other columns" in power query generates "m code" for you (that is the whole point of the query editor, it generates the m code for you rather then having to create it yourself). you can also type in the m code yourself, i believe it is table.selectcolumns () that returns a table with only the desired columns. kind regards djerro123. Tl;dr key takeaways : power query provides a dynamic and efficient method to remove null columns without hardcoding column names, making sure clean and adaptable datasets. the `table.profile. After filtering, add the column name [column] to the formula used to add the subtraction column and also implement the filter. this will porvide a list of the columns we want to delete. In this video, we will look at how we can drop empty columns in power query dynamically. we will use tranpose technique along with list.nonnullcount and record.tolist to achieve this.

I found this great power query code snippet online to dynamically return all columns where at least one row isn't null, so that i can select only the remaining columns that have values with table.selectcolumns. this effectively let's me to dynamically delete any null columns. Here is standard code to remove blanks for a single column, in this case "item description". #"filtered rows" = table.selectrows(#replacenull, each [item description] <> null and [item description] <> ""). In this article, mark proctor walks through a simple and efficient method for removing blank columns using power query. changing inputs into the perfect data often involves removing blank columns. if there are only a few blank columns it is straight forward; we select the columns and press [delete]. Using power query, you can remove null values from your dataset, ensuring it is clean, consistent, and reliable for accurate analysis and reporting. i will show you how to use power query to remove null values from a dataset in various scenarios.
