Query to write extra rows in Excel output - sql

Question

I'm trying to accomplish something that seems like it should be straightforward in MS Excel. I want to use a single SQL query - so I can pass it on to others to copy and paste - though I know the following could be achieved with other methods as well. Sheet 1 looks like this:
ID value value_type
1 minneapolis city_name
2 cincinnati city_name
I want an SQL query to return an "exploded" version of those two rows:
ID attr_name attr_value
1 value minneapolis
1 value_type city_name
2 value cincinnati
2 value_type city_name
There's much more I need to do, but this concept gets at the heart of the issue. I've tried a single SELECT statement, but can't seem to make it create two rows from one, and when I tried using UNION ALL I got a syntax error.
In Microsoft Query, how can I construct an SQL statement to create two rows from the existing values in one row?
UPDATE
thanks for the help so far. First, for reference, here is the default statement that recreates the table in Microsoft Query:
SELECT
`Sheet3$`.ID,
`Sheet3$`.name,
`Sheet3$`.name_type
FROM `path\testconvert.xlsx`.`Sheet3$` `Sheet3$`
So, following #lad2025's lead, I have:
SELECT
ID = `Sheet3$`.ID
,attr_name = 'value'
,attr_value = `Sheet3$`.value
FROM `path\testconvert.xlsx`.`Sheet3$` `Sheet3$`
UNION ALL
SELECT
ID = `Sheet3$`.ID
,attr_name = 'value_type'
,attr_value = `Sheet3$`.value_type
FROM `path\testconvert.xlsx`.`Sheet3$` `Sheet3$`
And the result is this error Too few parameters. Expected 4.

LiveDemo
CREATE TABLE #mytable(
ID INTEGER NOT NULL PRIMARY KEY
,value VARCHAR(11) NOT NULL
,value_type VARCHAR(9) NOT NULL
);
INSERT INTO #mytable(ID,value,value_type) VALUES (1,'minneapolis','city_name');
INSERT INTO #mytable(ID,value,value_type) VALUES (2,'cincinnati','city_name');
SELECT
ID
,[attr_name] = 'value'
,[attr_value] = value
FROM #mytable
UNION ALL
SELECT
ID
,[attr_name] = 'value_type'
,[attr_value] = value_type
FROM #mytable
ORDER BY id;

Answer 2

Ok, after going back to the original statement and working up from there as per the suggestions from #lad2025, I've come up with this statement which achieves what I was looking for in my original question:
SELECT
ID,
'name' AS [attr_name],
name AS [attr_value]
FROM `path\testconvert.xlsx`.`Sheet3$` `Sheet3$`
UNION ALL
SELECT
ID,
'name_type',
name_type
FROM `path\testconvert.xlsx`.`Sheet3$` `Sheet3$`
ORDER BY ID;
One of the main problems is that the new column names are only defined in the first SELECT statement. Also, brackets are ok, just not how #lad2025 was using them originally.
Microsoft Query is pretty finicky.
