Export "Product Gross Profit Contribution Analysis" to Excel with Java (Formula & Calculated Reports)

JQuick-ExcelFormula & Calculated Reports

Formula & Calculated ReportsScene 0095

Registers sales and cost per product, computing Gross Profit = Sales - Cost, Gross Margin = Gross Profit / Sales and Contribution Share = Gross Profit / Total Gross Profit, with the last row summarizing sales, cost and gross profit; the product with the lowest gross margin is marked in red. Implemented declaratively in pure XML — no Java business code required.

Product Gross Profit Contribution Analysis — Formula & Calculated Reports
Full screenshot of the exported xlsx

About this demo

This demo exports the "Product Gross Profit Contribution Analysis" workbook: 1 data sheet(s); MAPPING over 6 columns (产品名称, 销售额, 成本, 毛利, 毛利率, 贡献占比), 22 formula(s), 1 style rule(s). On the Java side it builds 6 data rows and calls exportProductMarginAnalysis() once — everything else is driven by the config.

It belongs to the "Formula & Calculated Reports" group: FORMULAS — inline expressions and aggregate functions such as Quantity × Unit Price or Balance = Receivable − Received, with SUM totals on the last row.

What you can copy from this page

  • The complete Java test class (62 lines, runnable as-is)
  • The complete XML config (36 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("sakuraPink", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Formulas0095ProductMarginAnalysisService service = factory.createApi(Formulas0095ProductMarginAnalysisService.class);

XML config · 0095_formulas_product-margin-analysis.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.
