I am trying to change the value of a single cell in power bi. When I go into the "data" view then right click and then go to "edit query" I have the option for "replace values". This works like a find and replace, the issue I am having is that if there are multiple cells with the same values they will all get changed. How can I just edit a single cell??
Unfortunately it is not as easy as just editing the cell. If you do not have an index/id column in your table then add one (there is a button on the toolbar to do this).
Then create a new custom column in M (PowerQuery / the data prep language of PowerBI), along the lines of:
NewColumn = IF ([Index] = "Index Number" and [YourColumn] = "<your value>")
THEN "The new text"
ELSE [YourOriginalColumn]
Rename or remove the original column and rename NewColumn to the original column name.

I m new to quicksight, I am trying to filter column in the quicksight, same way we do in excel.but i m getting blanks or not able to find how to filter.
Want to see only family which has gap point value as review,i.e the filter should only show (d,f) and not any other value or blanks
please help !!

If you are trying to filter a visualization, you need to:
Click the visualization to select it.
Click the "Filter" button on the left of the screen.
Click "Add filter"
Select the column you want to use for the filter (in this case "gap point value").
Edit the filter, and select the value "REVIEW", then click "Apply".

The picture I have attached shows what my power query table looks like (exactly the same as source file) and then underneath what I would like the final end product to look like.
Correct me if I'm wrong but I thought the purpose of power query/power bi was to not manipulate the source file but do this in power query/power bi?
If that's the case, how can I enter new columns and data to the existing table below?
You can add custom columns without manipulating source file in power bi. Please refer to below link.
https://learn.microsoft.com/en-us/power-bi/desktop-add-custom-column
EDIT: Based on your comment editing my answer - Not sure if this helps.
Click on edit queries after loading source file to power bi.
Using 'Enter Data' button entered sample data you provided and created new table. Data can be copy pasted from excel. You can enter new rows manually. Using Tag number column to keep reference.
Merge Queries - Once the above table is created merged it with original table on tag number column.
Expand Table - In the original table expand the merged table. Uncheck tag number(as it is already present) and uncheck use original column name as prefix.
Now the table will look like the way you wanted it.
You can always change data(add new columns/rows) manually in new table by clicking on gear button next to source.
Here is the closest solution to what I found from "manual data entry" letting you as much freedom as you would like to add rows of data, if the columns that you want to create do not follow a specific pattern.
I used an example for the column "Mob". I have not exactly reproduced the content of your cells but I hope that this will not be an issue to understand the logic.
Here is the data I am starting with:
Here is the Power Query in which I "manually" add a row:
#"Added Conditional Column" = Table.AddColumn(#"Changed Type", "Mob", each if [Tag Number] = "v" then null else null),
NewRows = Table.InsertRows(#"Added Conditional Column", 2, {[Mob="15-OHIO", Tag Number="4353654", Electronic ID=1.5, NLIS="", Date="31/05/2015", Live Weight="6", Draft="", Condition store="", Weighing Type="WEAN"]})
in
NewRows
1) I first created a column with only null values:
#"Added Conditional Column" = Table.AddColumn(#"Changed Type", "Mob", each if [Tag Number] = "v" then null else null),
2) With the "Table.InsertRows" function:
I indicated the specific line: 2, (knowing that power Bi start counting at zero, at the "headers" so it will the third line in the file)
I indicated the column at which I wanted to insert the value, i.e "Mob"
I indicated the value that all other other rows should have:
NewRows = Table.InsertRows(#"Added Conditional Column", 2, {[Mob="15-OHIO", Tag Number="4353654", Electronic ID=1.5, NLIS="", Date="31/05/2015", Live Weight="6", Draft="", Condition store="", Weighing Type="WEAN"]})
Here is the result:
I hope this helps.
You can apply this logic for all the other rows.
I do not think that this is very scalable however, becaue you have to indicate each time the values of the rows in the other columns as well. There might be a better option.
I have imported a JSON file into PowerBI and it contains a column in which the values are of type "List". I am looking to expand that column into multiple columns.
Specifically, the data contains a Sprint Name, the start date and the end date of the sprint, along with some other values associated with each sprint.
Trying to use "Expand to new rows" duplicates each sprint instance, creating a table that looks like this, duplicating each sprint instance multiple times for each associated value:
Sprint Name Value
JAN(S1Dev) 2019-01-01
JAN(S1Dev) 2019-01-13
JAN(S1Dev) {attribute}
JAN(S1Dev) {attribute}
JAN(S2Dev) 2019-01-14
JAN(S2Dev) 2019-01-31
JAN(S2Dev) {attribute}
JAN(S2Dev) {attribute}
FEB(S1Test) 2019-02-01
FEB(S1Test) 2019-02-15
... ...
I would like to do something similar to the "expand" feature, which instead creates a new column with each attribute rather than a new row. This is currently vastly increasing the size of my table for no reason, while also making the data practically un-useable. Any help would be appreciated, cheers!
I have found a very simple solution to this, but as it took me some time to figure it out I will answer my own question instead of deleting it to help others in the future...
Upon importing the JSON data into PowerBI first select "Convert to Table" to view the data as a table with editable properties.
Next, click the arrows pointing away from each other at the top of the column of Lists, and select "Extract Values".
Select a delimiter to use for concatenating values, I am choosing a comma since I know that the data contained within the list does not have any commas in it. If your data contains commas within it, choose something else. Similarly, if your data contains one of the delimiters, do not choose that as the delimiter.
It should now display a comma-separated list where it previously displayed "List" in orange text.
Now, right-click on the column and select "Split Column" then choose "By Delimiter"
Select the delimiter that you previously chose, and under "split at" select "Each occurrence of the delimiter" then click OK.
Your column should now be split into multiple columns based on the list!
Having imported an excel sheet into power query, I need to tidy it up by changing the value of a particular cell.
At the moment that cell has a null value, but there are other null values in the same column that I do not want to change. – So I cannot replace all of the null values in that column with another value.
I also cannot correct that particular cell in the source excel file (there are hundreds of them, which were created before I arrived).
I basically need some syntax for example that sets the value of cell H2 to “Jeep”, but not to change any other cells.
Very grateful for any insight.
One way would be:
In the Power Query Editor:
Add an index column starting from 1 (tab Add Column)
Add a Conditional column: If [Index] = 2 then Jeep else [H] (tab Add Column)
Delete Index column and [H] Column
Rename Custom column to [H].
I am new to power bi and would require your help to sort out below issue which I am facing.
Basically I am taking three columns into consideration as below:
Question: I would like to remove duplicate values from above table based on conditon "
Equal value for "Time" ,"ID" and Absolute difference in "Time spent" is lower or equal than 1"
as you can see in the image Rows highlighted falls in this category.
I would like to get these below rows removed based upon condition.

I am able to perform this in excel by making us of a fourth column with formulae =IF(AND(A3=A2,B3=B2,ABS(F3-F2)<1),"problem",0) and then filtering out the rows marked as probelm. Please help!!

I bet the suggestion from #Alexis Olson works just fine, but since you specifically mentioned the Query Editor, here's how I would do it there:
Have your data loaded like below, and just accept the changes made under Changed Type:
Don't worry about the other steps under the Query Settings. We'll get to that eventually.
Select Add Column and click Index Column, so that you get this:
Select Add Column, click Custom Column and insert this little formula in the appearing dialog box Table.AddColumn(#"Added Index", "Custom", each #"Added Index"[Time Spent]{[Index]}-#"Added Index"[Time Spent]{[Index]-1}):
Click OK, and make sure that you're getting this:
I think this step is a little weird, but you'll have to click 'Table' there in the column:
You will get an Error message in the first row, but you can remove that by right-clicking that column, and clicking Remove Errors:
Now you can click the drop-down menu in the Custom Column, select Number Filter and Does Not Equal
And insert 0, or select 0 from the drop-down menu in the dialog box:
This is it, your required numbers should now be filtered away:
Note, however, that this procedure comes at a cost since you're losing the first value due to the first step in the indexing. If the rest of this is something you can use, I can see if we can fix that last little part as well.
You can pick a representative [Time Spent] value from each unique set of rows by taking a max or min over the list of "duplicate" values. Here's the formula for such a custom column, which I'll call [Min Time]:
= List.Min(
Table.SelectRows(#"Previous Step",
(C) => (C[Time] = [Time] and
C[ID] = [ID] and
Number.Abs(C[Time Spent] - [Time Spent]) < 1)
)[Time Spent])
Once you have this custom column, you can group by [Time], [ID], and [Min Time] to roll up the duplicates and then rename the [Min Time] column to [Time Spent].
