How to mention individual sheet names while writing mutiple org.apache.spark.sql.Dataset into an .xls file using crealytics / spark-excel in java?

1 answer

I am trying to write different Java Datasets into an excel file which will contain multiple sheets inside it using crealytics/spark-excel library.

<dependency>             <groupId>com.crealytics</groupId>             <artifactId>spark-excel_2.11</artifactId>             <version>0.13.0</version> </dependency> 

How do I provide a name for those individual excel sheets?

Here's what I am trying to do:

import;  SparkSession spark = SparkSession.builder().appName("LineQuery").getOrCreate();  Dataset<Row> df1 = spark.sql("SELECT * FROM my_table1"); Dataset<Row> df2 = spark.sql("SELECT * FROM my_table2");  df1.write().format("com.crealytics.spark.excel").option("sheetName","My Sheet 1").option("header", "true").save("hdfs://" + outFile + ".xls");  df2.write().format("com.crealytics.spark.excel").option("sheetName","My Sheet 2").option("header", "true").mode(SaveMode.Append).save("hdfs://" + outFile + ".xls");

The best answer:

Use dataAddress option instead


>>> df = spark.createDataFrame([(11, 12), (21, 22)]) >>> +---+---+ | _1| _2| +---+---+ | 11| 12| | 21| 22| +---+---+ >>> df.where("_1 == 11").write.format("com.crealytics.spark.excel").option("dataAddress", "my sheet 1[#All]").option("header", "true").mode("append").save("/tmp/excel-df.xlsx") >>> df.where("_1 == 21").write.format("com.crealytics.spark.excel").option("dataAddress", "my sheet 2[#All]").option("header", "true").mode("append").save("/tmp/excel-df.xlsx")
