extends java.lang.Object

Excel builder

Example 1:

    final byte[] data = ExcelWriter
                           .createXlsx()
                           .withSheet("Persons", Person.class)
                             .withColumn("FirstName", Person::getFirstName)
                             .withColumn("LastName", Person::getLastName)
                             .withColumn("Age", Person::getAge)
                             .renderData(persons())
                             .autoSizeColumns()
                             .end()
                           .writeToBytes();
 

Example 2 (header row format):

    final byte[] data = ExcelWriter
                           .createXlsx()
                           .withFont("bold").bold().end()
                           .withFont("italic").italic().end()
                           .withCellStyle("header").font("bold").end()
                           .withSheet("Persons", Person.class)
                             .defaultHeaderStyle("header")
                             .withColumn("FirstName", Person::getFirstName)
                             .withColumn("LastName", Person::getLastName)
                             .withColumn("Age", Person::getAge)
                             .renderData(persons)
                             .renderData(getQueryStatistics())
                             .autoSizeColumns()
                             .end()
                           .writeToBytes();
 

Example 3 (footer SUM):

    final List<DataRecord> persons = persons();
    final byte[] data = ExcelWriter
                           .createXlsx()
                           .withSheet("Persons", Person.class)
                              .withColumn("FirstName")
                                 .colMapper(Person::getFirstName)
                                 .footerTextValue("SUM age")
                                 .end()
                              .withColumn("LastName")
                                 .colMapper(Person::getLastName)
                                 .end()
                              .withColumn("Age")
                                 .colMapper(Person::getAge)
                                 .footerSum()
                                 .end()
                              .renderData(persons)
                              .autoSizeColumns()
                              .end()
                           .writeToBytes();
 

Example 4 (footer SUM with styles):

    final List<DataRecord> persons = persons();
    final byte[] data = ExcelWriter
                           .createXlsx()
                           .withFont("bold").bold().end()
                           .withFont("bold-blue").bold().color(IndexedColors.BLUE).end()
                           .withCellStyle("header").font("bold").bgColor(IndexedColors.GREY_25_PERCENT).end()
                           .withCellStyle("age").format("#,##0").end()
                           .withCellStyle("sum-header").font("bold").end()
                           .withCellStyle("sum-age").font("bold-blue").format("#,##0").end()
                           .withSheet("Persons", Person.class)
                              .defaultHeaderStyle("header")
                              .withColumn("FirstName")
                                 .colMapper(Person::getFirstName)
                                 .footerTextValue("SUM age")
                                 .footerStyle("sum-header")
                                 .end()
                              .withColumn("LastName")
                                 .colMapper(Person::getLastName)
                                 .end()
                              .withColumn("Age")
                                 .colMapper(Person::getAge)
                                 .bodyStyle("age")
                                 .footerSum()
                                 .footerStyle("sum-age")
                                 .end()
                              .renderData(persons)
                              .autoSizeColumns()
                              .end()
                           .writeToBytes();
