Angular is a JS library for building user interfaces.
2022-08-19 02:26:17 +00:00
This demo tries to cover common Angular data flow ideas and strategies. Angular
and TypeScript familiarity is assumed.
**SheetJS plays nice with each version of Angular**.
Other demos cover general Angular deployments, including:

Angular tooling uses native NodeJS modules. There are a number of issues when
trying to run Angular projects with different NodeJS versions. These issues
should be directed to the Angular project.

:::caution
Angular CLI enables telemetry by default. When using a recent version, disable
analytics globally through the CLI tool before creating a new project:
```bash
npx @angular/cli analytics disable -g
```

## Installation
2022-10-30 05:45:37 +00:00
[The "Frameworks" section](/docs/getting-started/installation/frameworks) covers
2022-08-24 00:51:18 +00:00
installation with `pnpm` and other package managers.
2022-08-19 02:26:17 +00:00
The library can be imported directly from JS or TS code with:
```js
import { read, utils, writeFile } from 'xlsx';
```
## Internal State
The various SheetJS APIs work with various data shapes. The preferred state
depends on the application.
### Array of Objects
Typically, some users will create a spreadsheet with source data that should be
loaded into the site. This sheet will have known columns. For example, our
[presidents sheet](https://sheetjs.com/pres.xlsx) has "Name" / "Index" columns:
![`pres.xlsx` data](pathname:///pres.png)
This naturally maps to an array of typed objects, as in the TS example below:
```ts
import { read, utils } from 'xlsx';
interface President {
Name: string;
Index: number;
}
const f = await (await fetch("https://sheetjs.com/pres.xlsx")).arrayBuffer();
const wb = read(f);
const data = utils.sheet_to_json<President>(wb.Sheets[wb.SheetNames[0]]);
console.log(data);
```
`data` will be an array of objects:
```js
[
{ Name: "Bill Clinton", Index: 42 },
{ Name: "GeorgeW Bush", Index: 43 },
{ Name: "Barack Obama", Index: 44 },
{ Name: "Donald Trump", Index: 45 },
{ Name: "Joseph Biden", Index: 46 }
]
```
2022-08-19 06:42:18 +00:00
A component will typically loop over the data using `*ngFor`. The following
2022-08-19 02:26:17 +00:00
example generates a TABLE with a row for each President:
```ts title="src/app/app.component.ts"
import { Component } from '@angular/core';
2022-08-19 06:42:18 +00:00
import { read, utils, writeFileXLSX } from 'xlsx';
2022-08-19 02:26:17 +00:00
interface President { Name: string; Index: number };
@Component({
selector: 'app-root',
template: `
<div class="content" role="main"><table>
<thead><th>Name</th><th>Index</th></thead>
<tbody>
// highlight-start
<tr *ngFor="let row of rows">
<td>{{row.Name}}</td>
<td>{{row.Index}}</td>
</tr>
// highlight-end
2022-08-19 06:42:18 +00:00
</tbody><tfoot>
<button (click)="onSave()">Export XLSX</button>
</tfoot>
2022-08-19 02:26:17 +00:00
</table></div>
`
})
export class AppComponent {
// highlight-next-line
rows: President[] = [ { Name: "SheetJS", Index: 0 }];
ngOnInit(): void { (async() => {
/* Download from https://sheetjs.com/pres.numbers */
const f = await fetch("https://sheetjs.com/pres.numbers");
const ab = await f.arrayBuffer();
/* parse workbook */
// highlight-next-line
const wb = read(ab);
/* update data */
// highlight-next-line
this.rows = utils.sheet_to_json<President>(wb.Sheets[wb.SheetNames[0]]);
})(); }
2022-08-19 06:42:18 +00:00
/* get state data and export to XLSX */
onSave(): void {
// highlight-next-line
const ws = utils.json_to_sheet(this.rows);
const wb = utils.book_new();
utils.book_append_sheet(wb, ws, "Data");
writeFileXLSX(wb, "SheetJSAngularAoO.xlsx");
}

2023-07-25 02:31:22 +00:00
0) Disable telemetry:
```bash
npx @angular/cli analytics disable -g
```
1) Create a new project:
2023-02-21 08:40:30 +00:00
2023-07-25 02:31:22 +00:00
```bash
npx @angular/cli new --minimal --defaults --no-interactive sheetjs-angular
```
2023-02-21 08:40:30 +00:00
2) Install the SheetJS dependency and start the dev server:
2023-05-07 13:58:36 +00:00
<CodeBlock language="bash">{`\
2023-02-21 08:40:30 +00:00
cd sheetjs-angular
2023-05-07 13:58:36 +00:00
npm i
2023-04-27 09:12:19 +00:00
npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz
2023-02-21 08:40:30 +00:00
npx @angular/cli analytics disable
2023-04-27 09:12:19 +00:00
npm start`}
2023-05-07 13:58:36 +00:00
</CodeBlock>
2023-02-21 08:40:30 +00:00
3) Open a web browser and access the displayed URL (`http://localhost:4200`)
4) Replace `src/app/app.component.ts` with the code snippet.
The page will refresh and show a table with an Export button. Click the button
2023-07-25 02:31:22 +00:00
and the page will attempt to download `SheetJSAngularAoO.xlsx`.
5) Stop the dev server and build the site:
```bash
npm run build
```
To test the generated site, start a web server:
```bash
npx -y http-server dist/sheetjs-angular/
```
2023-02-21 08:40:30 +00:00
Access `http://localhost:8080` with a web browser to test the bundled site.

### HTML
The main disadvantage of the Array of Objects approach is the specific nature
of the columns. For more general use, passing around an Array of Arrays works.
However, this does not handle merge cells well!
The `sheet_to_html` function generates HTML that is aware of merges and other
worksheet features. The generated HTML does not contain any `<script>` tags,
and should therefore be safe to pass to an `innerHTML`-bound variable, but the
`DomSanitizer` approach is strongly recommended:
```ts title="src/app/app.component.ts"
2022-08-19 06:42:18 +00:00
import { Component, ElementRef, ViewChild } from '@angular/core';
2022-08-19 02:26:17 +00:00

2022-08-19 02:26:17 +00:00
})
export class AppComponent {
// highlight-start
constructor(private sanitizer: DomSanitizer) {}
html: SafeHtml = "";
2022-08-19 06:42:18 +00:00
@ViewChild('tableau') tabeller!: ElementRef<HTMLDivElement>;
2022-08-19 02:26:17 +00:00
// highlight-end
ngOnInit(): void { (async() => {
/* Download from https://sheetjs.com/pres.numbers */
const f = await fetch("https://sheetjs.com/pres.numbers");
const ab = await f.arrayBuffer();
/* parse workbook */
const wb = read(ab);
/* update data */
// highlight-start
const h = utils.sheet_to_html(wb.Sheets[wb.SheetNames[0]]);
this.html = this.sanitizer.bypassSecurityTrustHtml(h);
// highlight-end
})(); }
2022-08-19 06:42:18 +00:00
/* get live table and export to XLSX */
onSave(): void {
// highlight-start
const elt = this.tabeller.nativeElement.getElementsByTagName("TABLE")[0];
const wb = utils.table_to_book(elt);
// highlight-end
writeFileXLSX(wb, "SheetJSAngularHTML.xlsx");
}

### Rows and Columns
Some data grids and UI components split worksheet state in two parts: an array
of column attribute objects and an array of row objects. The former is used to
generate column headings and for indexing into the row objects.
The safest approach is to use an array of arrays for state and to generate
2022-08-23 03:20:02 +00:00
column objects that map to A1-Style column headers.
2022-08-19 02:26:17 +00:00
`ngx-datatable` uses `prop` as the key and `name` for the column label:
```js
/* rows are generated with a simple array of arrays */
this.rows = utils.sheet_to_json(worksheet, { header: 1 });
/* column objects are generated based on the worksheet range */
const range = utils.decode_range(ws["!ref"]||"A1");
this.columns = Array.from({ length: range.e.c + 1 }, (_, i) => ({
/* for an array of arrays, the keys are "0", "1", "2", ... */
prop: String(i),
/* column labels: encode_col translates 0 -> "A", 1 -> "B", 2 -> "C", ... */
name: XLSX.utils.encode_col(i)
}));
```
## Older Versions
:::warning
This demo is included for legacy deployments. There are incompatibilities with
different NodeJS and other ecosystem versions. Issues should be raised with
Google and the Angular team.
**The newest versions of NodeJS will not work with older Angular projects!**
:::
:::caution
2023-07-06 07:21:41 +00:00
The Angular tooling does not provide a command to switch between versions!
2022-08-19 02:26:17 +00:00
2022-10-19 10:05:59 +00:00
This is a known Angular problem.
2022-08-19 02:26:17 +00:00
To work around this, [`SheetJSAngular.zip`](pathname:///angular/SheetJSAngular.zip)
is a skeleton project designed to play nice with each Angular version.
:::
### Strategies
#### Internal State
This demo uses an array of arrays as the internal state:
```ts
export class SheetJSComponent {
data: any[][] = [ [1, 2], [3, 4] ];
// ...
}
```
Nested `ngFor` in a template can loop across the rows and cells:
```html
<table class="sjs-table">
<tr *ngFor="let row of data">
<td *ngFor="let val of row">{{val}}</td>
</tr>
</table>
```
#### Reading Data
For legacy deployments, the best ingress is a standard HTML INPUT file element:
```html
<input type="file" (change)="onFileChange($event)" multiple="false" />
```
In the component, the event is a standard file event. Using a `FileReader` has
broad support compared to the modern `Blob#arrayBuffer` approach:
```ts
onFileChange(evt: any) {
/* wire up file reader */
const target: DataTransfer = <DataTransfer>(evt.target);
if (target.files.length !== 1) throw new Error('Cannot use multiple files');
const reader: FileReader = new FileReader();
reader.onload = (e: any) => {
/* read workbook */
const ab: ArrayBuffer = e.target.result;
// highlight-next-line
const wb: WorkBook = read(ab);
/* grab first sheet */
const wsname: string = wb.SheetNames[0];
const ws: WorkSheet = wb.Sheets[wsname];
/* save data */
// highlight-next-line
this.data = <AOA>(utils.sheet_to_json(ws, {header: 1}));
};
reader.readAsArrayBuffer(target.files[0]);
}
```
#### Writing Data
The demo uses an HTML5 button in the template:
```html
<button (click)="export()">Export!</button>
```
In the component, `aoa_to_sheet` is used to generate the worksheet:
```ts
export(): void {
/* generate worksheet */
const ws: WorkSheet = utils.aoa_to_sheet(this.data);
/* generate workbook and add the worksheet */
const wb: WorkBook = utils.book_new();
utils.book_append_sheet(wb, ws, 'Sheet1');
/* save to file */
writeFile(wb, "SheetJS.xlsx");
}
```
### SystemJS
The default angular-cli configuration requires no additional configuration.
Some deployments use the SystemJS loader, which does require configuration.
2022-10-30 05:45:37 +00:00
[The SystemJS demo](/docs/demos/bundler#systemjs) describe the required settings.
