Split cdt

You'll need to split the second string on the semicolon - I assume that the semicolon is always used to separate the items? Then, you will need to create a couple of loops to loop through the items and create your new array. Lastly, I used a!flatten() to make it a single list instead of a list of lists. See a sample here:

a!localVariables(
  local!array: {{id:1, name:"abc"},{id:2,name:"abc;pqr"}},
  a!flatten(
    a!forEach(
      items: local!array,
      expression: a!localVariables(
        local!id: fv!item.id,
        a!forEach(
          items: split(fv!item.name, ";"),
          expression: {
            id: local!id,
            name: fv!item
          }
        )
      )
    )
  )
)
