I have a number greater than 10 digit and that stored as a text Is there any way to sort them?

If you mean you have a CDT/Dictionary array of data and you want to sort ascending (or descending) on that field then you can use the following code.

a!localVariables(
  local!numberOfEntries: 10,
  local!data: a!forEach(
    items: 1 + enumerate(local!numberOfEntries),
    expression: {
      id: fv!item,
      number: concat(round(rand(12) * 9, 0))
    }
  ),
  index(
    todatasubset(
      local!data,
      a!pagingInfo(
        startIndex: 1,
        batchSize: -1,
        sort: a!sortInfo(
          field: "number",
          ascending: true
        )
      )
    ),
    "data",
    {}
  )
)

Thanks for the solution

This is not working for input {"3504051867","350405187","350405188","350405189","3604051899","360405189"}

can you please check 

a!localVariables(
  local!data: {"3504051867","350405187","350405188","350405189","3604051899","360405189"},
  local!convertDataToDictionary: a!forEach(
    items: local!data,
    expression: {
      number: fv!item
    }
  ),
  index(
    todatasubset(
      local!convertDataToDictionary,
      a!pagingInfo(
        startIndex: 1,
        batchSize: -1,
        sort: a!sortInfo(
          field: "number",
          ascending: true
        )
      )
    ),
    "data",
    {}
  )
)

I have sorted in  descending order and The highlighted number should be the second number but it is sorting based on ascii value so it is giving wrong sorting order.

Ah. Yes. I only really looked when they were all the same length. I'll have a think.

Edit: It's starting to feel a little clunky but here it is. I'll also update the code above just in case anyone ever uses it

a!localVariables(
  local!data: {"3504051867","350405187","350405188","350405189","3604051899","360405189"},
  local!maxNumberLength: max(len(local!data)),
  local!convertDataToDictionary: a!forEach(
    items: local!data,
    expression: a!localVariables(
      local!length: len(fv!item),
      local!numberOfLeadingZeros: tointeger(local!maxNumberLength - local!length),
      {
        number: fv!item,
        numberWithLeadingZeros: concat(
          repeat(local!numberOfLeadingZeros, 0),
          fv!item
        )
      }
    )
  ),
  local!orderedNumbers: index(
    index(
      todatasubset(
        local!convertDataToDictionary,
        a!pagingInfo(
          startIndex: 1,
          batchSize: -1,
          sort: a!sortInfo(
            field: "numberWithLeadingZeros",
            ascending: false
          )
        )
      ),
      "data",
      {}
    ),
    "number",
    {}
  ),
  local!orderedNumbers
)

Thanks!! Its working

Pad all strings with spaces to make text sort working, then sort and remove the spaces.

a!localVariables(
  local!numbers:{"99", "10", "9999999999999", "3504051867", "1", "350405187","350405188","350405189","3604051899","360405189"},
  trim(
    todatasubset(
      a!forEach(
        items: local!numbers,
        expression: a!map(value: padleft(fv!item, 20))
      ),
      a!pagingInfo(
        startIndex: 1,
        batchSize: -1,
        sort: a!sortInfo(
          field: "value",
          ascending: true
        )
      )
    ).data.value
  )
)

Thanks For the solution
