Though we have tried with `Transform Specs` using `cast` function Still we couldn't able to achieve it.
```js
"transformSpec": {
"transforms": [
{
"type": "expression",
"name": "edata_visits_index",
"expression": "cast(edata_visits_index,'LONG')"
}
]
}
```
**Output:**
```js
[
{
"segmentId": "datasource-events-33_2019-11-07T00:00:00.000Z_2019-11-08T00:00:00.000Z_2019-02-26T07:42:38.349Z",
"columns": [
"edata_visits_index"
],
"events": [
{
"__time": 1573146630927,
"edata_visits_index": "0"
}
]
}
]
```
Any other alternative solution to convert the `String` value into `Long` type
