# Clase FormatCase
<a name="aws-glue-api-pyspark-transforms-FormatCase"></a>

La transformación `FormatCase` cambia cada cadena de una columna al tipo de mayúsculas y minúsculas especificado.

## Ejemplo
<a name="pyspark-FormatCase-examples"></a>

```
from pyspark.context import SparkContext
from pyspark.sql import SparkSession
from awsgluedi.transforms import *

sc = SparkContext()
spark = SparkSession(sc)

datasource1 = spark.read.json("s3://${BUCKET}/json/zips/raw/data")

try:
    df_output = data_cleaning.FormatCase.apply(
        data_frame=datasource1,
        spark_context=sc,
        source_column="city",
        case_type="LOWER"
    )    
except:
    print("Unexpected Error happened ")
    raise
```

## Output
<a name="pyspark-FormatCase-output"></a>

 La transformación `FormatCase` convertirá los valores de la columna “city” a minúsculas según el parámetro “case\$1type="LOWER"”. El elemento DataFrame “df\$1output” resultante contendrá todas las columnas de la “datasource1” original, pero con los valores de la columna “city” en minúsculas.

<a name="aws-glue-api-pyspark-transforms-FormatCase-__call__"></a>

La transformación `FormatCase` cambia cada cadena de una columna al tipo de mayúsculas y minúsculas especificado.
+ `source_column`: el nombre de una columna existente.
+ `case_type`: los tipos de mayúsculas y minúsculas admitidos son `CAPITAL`, `LOWER`, `UPPER`, `SENTENCE`.
