How to add Spark-excel to PySpark - apache-spark

Question

I'm trying to read xlsx to PySpark and tried with multiple ways to import the library of Spark-excel but I still get errors while reading xlsx file.
I'm using Spark with standalone mode on my Mac.
My code:
# spark configuration
spark_path = "/spark/spark-3.0.1-bin-hadoop2.7"
findspark.init(spark_path)
spark = SparkSession.builder.master("local").appName("Word Count").config("--packages com.crealytics:spark-excel_2.12:0.13.7").getOrCreate()
data_location = "bank_transactions.xlsx"
df = spark.read.format("com.crealytics.spark.excel").load(data_location)
I got the following error:
Py4JJavaError: An error occurred while calling o37.load.

Solutions:
Download proper spark-excel library, for me it's:
https://mvnrepository.com/artifact/com.crealytics/spark-excel_2.12/0.13.7
Create directory spark_jars in the SPARK_HOME then store the spark-excel package in spark_jars directory
Add the spark_jars to spark.executor.extraClassPath of Spark session:
findspark.init(spark_path)
spark = SparkSession.builder.master("local") \
.appName("Word Count") \
.config("spark.jars.packages","com.crealytics:spark-excel_2.12:0.13.7") \
.getOrCreate()
spark
