I was trying to reindex a large index when I discovered that there are trailing \r\n in the end of all values of a field. Since the mapping in the new index for this field is a double, and not a string, it crashes.

How do I replace/trim these values to in the reindex process?

If all you want to do is trim whitespace on the one field, you can set up an [ingest pipeline](https://www.elastic.co/guide/en/elasticsearch/reference/7.0/ingest.html) with the [trim processor](https://www.elastic.co/guide/en/elasticsearch/reference/7.0/trim-processor.html) set up for the field, then specify the pipeline in your reindex request like so:

```auto
POST _reindex
{
  "source": {
    "index": "source_index"
  },
  "dest": {
    "index": "dest_index",
    "pipeline": "trim_my_double_field_pipeline"
  }
}

```

(above example pulled with minor changes from the [Reindex docs](https://www.elastic.co/guide/en/elasticsearch/reference/7.0/docs-reindex.html))

Alternatively, you could use a script in the reindex request, but using an ingest pipeline is probably easier.
