I want to load a .xlsx file to DLT but struggling as it is not available with Autoloader.

With the Assistant I tried to load the .xlsx first to a data frame and then send it to DLT.

import dlt
from pyspark.sql import SparkSession

# Load xlsx file into DataFrame
df = spark.read \
    .format("com.crealytics.spark.excel") \
    .option("dataAddress", "${my_etl.sheet_address}") \
    .option("header", "${my_etl.header}") \
    .option("inferSchema", "${my_etl.infer_schema}") \
    .option("timestampFormat", "${my_etl.timestamp_format}") \
    .load("${my_etl.input_path}")

@dlt.table
def conformed():
    return df

but it is not working.
