We'll +explore how to load SheetJS in an OpenUI5 app and handle data binding with the +Model-View-Controller pattern. + +## Installation + +[The "Frameworks" section](/docs/getting-started/installation/frameworks) covers +installation with Yarn and other package managers. + +The library should be loaded via script tag in your HTML: + + + {``} + + +This will expose the `XLSX` global object which contains all the necessary methods. + + +## Internal State + +The various SheetJS APIs work with various data shapes. The preferred state +depends on the application. + +### JSON Model + +The OpenUI5 JSON Model provides ideal integration for spreadsheet data, enabling direct UI control binding. + +#### State + +The example [presidents sheet](https://docs.sheetjs.com/pres.xlsx) has one +header row with "Name" and "Index" columns. The natural JS representation is an +object for each row, using the values in the first rows as keys: + + + +

+ +The OpenUI5 `JSONModel`[^1] is a client-side model implementation that stores data as JSON. +Here's a basic example of initializing a model, with a more complete implementation shown later: + + + + +```js +sap.ui.define(["sap/ui/model/json/JSONModel"], function (JSONModel) { + const oModel = new JSONModel({ presidents: [] }); +}); +``` + + + + +#### Updating State + +The SheetJS [`read`](/docs/api/parse-options) and [`sheet_to_json`](/docs/api/utilities/array#array-output) +functions simplify state updates.

They are typically used in event handlers attached to buttons or other elements. + +A button press handler can generate a local file when clicked: + +```mermaid +flowchart LR + state((oModel\ngetProperty)) + ws(SheetJS\nWorksheet) + wb(SheetJS\nWorkbook) + file[(XLSX\nexport)] + state --> |json_to_sheet\n\n| ws + ws --> |book_new\nbook_append_sheet| wb + wb --> |writeFile\n\n| file +``` + +```js +/* get model data and export to XLSX */ + onExport: function() { + const data = this.getView().getModel().getProperty("/presidents"); + /* generate worksheet from model data */ + // highlight-next-line + const ws = XLSX.utils.json_to_sheet(data); + /* create workbook and append worksheet */ + const wb = XLSX.utils.book_new(); + XLSX.utils.book_append_sheet(wb, ws, "Data"); + /* export to XLSX */ + XLSX.writeFileXLSX(wb, "SheetJSOpenUI5AoO.xlsx"); + } +``` + + +#### Complete Component + +This complete component example fetches a test file and displays the contents in a table. +When the export button is clicked, an event handler will export a file: + +```xml title="webapp/view/Main.view.xml" + + + + + + +
