Export "Store Daily Sales Summary" to Excel with Java (Merge & Grouped Reports)

JQuick-ExcelMerge & Grouped Reports

Merge & Grouped ReportsScene 0055

Groups the day's sales amount and transaction count by category per store, with a subtotal row after each store and a grand total for all stores in the last row; the store-name column is vertically merged into one block. Java only groups and pre-processes the rows; all statistics and layout are declared in XML.

About this demo

This demo exports the "Store Daily Sales Summary" workbook: 1 data sheet(s); MAPPING over 4 columns (门店, 品类, 销售额, 销售笔数), 10 formula(s), 5 style rule(s). On the Java side it only builds the data and calls exportStoreSalesSummary() once — everything else is driven by the config.

It belongs to the "Merge & Grouped Reports" group: MERGE group blocks with SUBTOTAL/TOTAL rows: each group column merges into one vertical block, every group closes with a subtotal and the report ends with a grand total.

What you can copy from this page

  • The complete Java test class (88 lines, runnable as-is)
  • The complete XML config (38 lines: mapping, formulas, styles, charts and every other rule)
  • The exported xlsx file (real output, comparable with the preview above)

Minimal invocation (4 lines)

The core is these four lines: hand the rows to the parser, the parser to the factory, get a typed Service and call it. Copy them straight into your project.

// rows 由业务代码构造（List<JQuickRow>），os 为输出流，见下方完整源码
JQuickParseHandler parser = new JQuickExcelExportXmlParseFactory("crimsonRed", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Merge0055StoreSalesSummaryService service = factory.createApi(Merge0055StoreSalesSummaryService.class);

XML config · 0055_merge_store-sales-summary.xml

Formats (FORMAT), formulas (FORMULAS) and styles (STYLE) are all declared in this XML, fully decoupled from the Java code. The full config is below — copy it as-is.
