Have a look at crosstab queries used with Min, Max and Last.

Transpose:

TRANSFORM First(Table1_1.Data) AS FirstOfData
SELECT Table1_1.FileName, Table1_1.ObjectName
FROM Table1_1
GROUP BY Table1_1.FileName, Table1_1.ObjectName
PIVOT Table1_1.Column;

Normalize:

SELECT FileName, ObjectName, "Column1" As ColName, Column1 As ColData  
FROM Table1 
UNION ALL
SELECT FileName, ObjectName, "Column2" As ColName, Column2 As ColData  
FROM Table1 
UNION ALL
SELECT FileName, ObjectName, "Column3" As ColName, Column3 As ColData  
FROM Table1 
UNION ALL
SELECT FileName, ObjectName, "Column4" As ColName, Column4 As ColData  
FROM Table1 
UNION ALL
SELECT FileName, ObjectName, "Column5" As ColName, Column5 As ColData  
FROM Table1
