Export "Fixed Asset Depreciation Ledger" to Excel with Java (Merge & Grouped Reports)

JQuick-ExcelMerge & Grouped Reports

Merge & Grouped ReportsScene 0015

Fixed assets grouped in two levels (Asset Category → Asset Name), computing Original Value = Quantity × Unit Price and Net Value = Original Value - Accumulated Depreciation per row; a subtotal row follows each asset category and a grand total for all categories appears at the end; the asset-category column is vertically merged into one block. Java only groups and pre-processes the rows; all statistics and layout are declared in XML.

Fixed Asset Depreciation Ledger — Merge & Grouped Reports

About this demo

This demo exports the "Fixed Asset Depreciation Ledger" workbook: 1 data sheet(s); MAPPING over 7 columns (资产类别, 资产名称, 数量, 单价, 原值, 已提折旧, 净值), 26 formula(s), 5 style rule(s). On the Java side it only builds the data and calls exportFixedAssetLedger() 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 (98 lines, runnable as-is)
  • The complete XML config (40 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("skyBlue", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Merge0015FixedAssetLedgerService service = factory.createApi(Merge0015FixedAssetLedgerService.class);

XML config · 0015_merge_fixed-asset-ledger.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.
