Goutam Pradhan :

UDF:
def myudf2=(input:String)=>{
    val regex = "('\\d+':'\\d+')".r
    val out = new ListBuffer[String]()
    input.replaceAll("'", "").split(",").map(x=>{
      if(x.matches("(\\d+:\\d+)")){
        val colon = x.split(":")
        out += (colon(0).toInt to colon(1).toInt).mkString(", ")
      } else {
        out += x
      } 
    })
    out.mkString(",").replaceAll("\\[|\\]", "")
  }

val df = Seq((1,"'1':'5','6','7':'10'"),(2,"'1':'6','7','8':'12'")).toDF("id","number")
scala> df.show
+---+--------------------+
| id|              number|
+---+--------------------+
|  1|'1':'5','6','7':'10'|
|  2|'1':'6','7','8':'12'|
+---+--------------------+
val myCostumeudf = udf(myudf2)
scala> val outDF = df.withColumn("output", myCostumeudf(df("number")))
scala> outDF.show(5,false)
+---+--------------------+---------------------------------------+
|id |number              |output                                 |
