Customer Complaint Handling Ledger — Formula & Calculated Reports
Full screenshot of the exported xlsx

About this demo

This demo exports the "Customer Complaint Handling Ledger" workbook: 1 data sheet(s); MAPPING over 7 columns (投诉单号, 客户, 投诉类型, 受理日期, 处理时限(天), 实际处理天数, 是否超期), 2 formula(s), 1 style rule(s). On the Java side it builds 7 data rows and calls exportCustomerComplaintLedger() 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 (75 lines, runnable as-is)
  • The complete XML config (32 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("pearl", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Formulas0058CustomerComplaintLedgerService service = factory.createApi(Formulas0058CustomerComplaintLedgerService.class);

XML config · 0058_formulas_customer-complaint-ledger.xml
