Indexing to Lis of text String

Can you share your code? I am sure I understand what you do and what your goal is.

Hi Stefan,
Here is my code.

a!localVariables(
  local!exceldata: readexcelsheet(
    excelDocument: cons!IT_SAMPLE_FILE,
    sheetNumber: 0,
    startRow: 0,
    /*stopReadingAtFirstBlankRow: false(),*/
    /*pagingInfo: a!pagingInfo(startIndex: 1, batchSize: 0)*/
    
  ),
  local!datalength: length(
    index(local!exceldata, "result", "values", {})
  ),
  local!headers: index(local!exceldata, "result", "values", 1, {}),
  local!filecdt: a!forEach(
    items: local!headers[1],
    expression: {
      fv!item & " : " & a!forEach(
        items: 2,
        /*enumerate(local!datalength - 1) + 2,*/
        expression: a!forEach(
          items: index(
            local!exceldata,
            "result",
            "values",
            fv!item,
            {}
          ),
          expression: a!forEach(
            items: fv!item,
            expression: a!forEach(
              items: fv!item,
              expression: fv!item
            )
          )
        )
      )
    }
  ),
  local!filecdt
)

This is confusing. Why do you use more than three parameters with the index function? The behaviour with more than three parameters is undefined.

Could you please put some light on the functionality what you are trying to achieve. What is the output you are getting and what you are expecting for the same?

index(local!exceldata, "result", "values", 1, {}) is equivalent to
index(index(index(local!exceldata, "result",{}),"values",{}),1,{})

Try using the a!flatten() function to remove this multiple levels of lists and then it should be easier. 

Sorry, but again, while this behaviour works most of the times, it is no documented and has edge cases in which it does not work and is super difficult to debug.

Could you please help me in with the issue I am facing ?
"I am trying to use indexing for type " List of Text String " but the output i am getting not the expected output"

What is the input and what output you are expecting?

The input is like : "How","Are","You" (which is of type list of  text strings),
I am trying to get only 1 at a time using indexing (either "How" or "Are" or "You"), But I am getting the "H","A","R" if i am using index 1
