edited November 2018 in Help
Hello, please sorry for my english)

i use  operator  "Loop Attributes"  and in this operators i use operator "Set Macro" and Generate Attributes. I have Matrix that have 0 and 1. I try to change Value in the fields which has 1 and  put there the Column Name. 

in Set Macro i wrote in Macro field "atts" and value field "%{loop_attribute}"
and in Generate Attributes i wrote in attribute name "%{atts}" and in the function expression field "if(%{atts}==1,str(%{atts}),"")"

but it still generate Matrix only with 1, without columnNames.

Please help me)

    Hi sorry, I don't get the point. Are you trying to convert the first row of your input data into column headers? Usually you can do that already during the data import, e.g. by defining the Name annotation for the first row in the Read CSV or Read Excel configuration wizard.

    If you still have problems, please post a short sample of your data and describe your problem more detailed. Also, if you have problems with the import wizard or if I did understand your issue completely wrong, please let me know.

    Best regards,
    Marius

    i have Table with 1 and 0
            ColumnName1ColumnName2
    Row 1        1              0
    Row2        0              1
    i try to change it to
                    ColumnName1                      ColumnName2
    Row 1        ColumnName1               
    Row2                                                      ColumnName2

    it seem so that i can read the column name, but if i use operator Generate Attributes with funktion: name "%{atts}" and in the function expression field "if(%{atts}==1,str(%{atts}),"")", i became table with 1 and without 0
            ColumnName1ColumnName2
    Row 1        1               
    Row2                        1

    You need to put quotes around the macro in the result of the if statement.
