Export "Budget vs. Actual Variance Analysis" to Excel with Java (Styled & Formatted Reports)

JQuick-ExcelStyled & Formatted Reports

Styled & Formatted ReportsScene 0019

Compares budget and actual by expense account, computing Variance = Actual - Budget and Variance Rate = Variance / Budget per row, with a total row at the end; the conclusion cell of accounts concluded as "Over Budget" is marked in red font. Implemented declaratively in pure XML — no Java business code required.

About this demo

This demo exports the "Budget vs. Actual Variance Analysis" workbook: 1 data sheet(s); MAPPING over 6 columns (费用科目, 预算金额, 实际金额, 差异, 差异率, 结论), 18 formula(s), 1 style rule(s). On the Java side it builds 7 data rows and calls exportBudgetVariance() once — everything else is driven by the config.

It belongs to the "Styled & Formatted Reports" group: STYLE and conditional formatting: themed headers, zebra striping, highlighted total rows and threshold-based colouring of abnormal cells.

What you can copy from this page

  • The complete Java test class (62 lines, runnable as-is)
  • The complete XML config (35 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("slate", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Style0019BudgetVarianceService service = factory.createApi(Style0019BudgetVarianceService.class);

XML config · 0019_style_budget-variance.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.
