`table_to_book` / `table_to_sheet` / `sheet_add_dom` act on HTML DOM elements.

Traditionally there is no DOM in server-side environments.

SheetJS offers three methods to directly process HTML DOM TABLE elements[^1]:

:::note

- `table_to_sheet` generates a SheetJS worksheet[^2] from a TABLE element

- `table_to_book` generates a SheetJS workbook[^3] from a TABLE element

This demo covers synthetic DOM implementations for non-browser platforms.
|
||||
|
||||
## Integration Details
|
||||
|
||||
SheetJS API methods use DOM features that may not be available.
|
||||
|
||||
### Table rows
|
||||
|
||||
The `rows` property of TABLE elements is a list of TR row children. This list
|
||||
automatically updates when rows are added and deleted.
|
||||
|
||||
SheetJS does not mutate `rows`. Assuming there are no nested tables, the `rows`
|
||||
property can be created using `getElementsByTagName`:
|
||||
|
||||
```js
|
||||
tbl.rows = Array.from(tbl.getElementsByTagName("tr"));
|
||||
```
|
||||
|
||||
### Row cells
|
||||
|
||||
The `cells` property of TR elements is a list of TD cell children. This list
|
||||
automatically updates when cells are added and deleted.
|
||||
|
||||
SheetJS does not mutate `cells`. Assuming there are no nested tables, the
|
||||
`cells` property can be created using `getElementsByTagName`:
|
||||
|
||||
```js
|
||||
tbl.rows.forEach(row => row.cells = Array.from(row.getElementsByTagName("td")));
|
||||
```

||||

### Internal State
|

|

:::
|
||||
The ["Angular" demo](/docs/demos/frontend/angular) discusses a number of state
|
||||
representations and preview strategies.
|
||||
|
||||
### Angular
|
||||
For this demo, the internal state is an "array of arrays"[^1] (`any[][]`):
|
||||
|
||||
`Array<Array<any>>` neatly maps to a table with `ngFor`:
|
||||
```ts title="Array of Arrays state"

||||
type AOA = any[][];
|
||||

||||
export class SheetJSTablePage {

||||
data: AOA = [
|
||||
["S", "h", "e", "e", "t", "J", "S"],
|
||||
[ 5, 4, 3, 3, 7, 9, 5]
|
||||
];
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
### Displaying Data
|
||||
|
||||
`ion-grid`[^2] is a display grid component. The Angular `ngFor` directive[^3]
|
||||
simplifies iteration over the array of arrays:
|
||||
|
||||
```html title="Template for displaying an array of arrays"
|
||||
<ion-grid>
|
||||
<ion-row *ngFor="let row of data">

`readAsArrayBuffer` returns `ArrayBuffer` objects suitable for `array` type:

modules in the `@awesome-cordova-plugins` scope should be used.

#### Reading Files
|
||||
|
||||
`this.file.readAsArrayBuffer` reads file data from a specified URL and resolves
|
||||
to `ArrayBuffer` objects.
|
||||
|
||||
These objects can be parsed with the SheetJS `read` method[^4]. The SheetJS
|
||||
`sheet_to_json` method[^5] with the option `header: 1` generates an array of
|
||||
arrays which can be assigned to the page state:
|
||||
|
||||
```ts
|
||||
/* read a workbook */
|
||||
/* read a workbook file */
|
||||
const ab: ArrayBuffer = await this.file.readAsArrayBuffer(url, filename);
|
||||
/* parse */
|
||||
const wb: XLSX.WorkBook = XLSX.read(ab, {type: 'array'});
|
||||
/* generate an array of arrays from the first worksheet */
|
||||
const ws: XLSX.WorkSheet = wb.SheetNames[wb.Sheets[0]];

_Writing Files_
|
||||
#### Writing Files
|
||||
|
||||
`array` type can be converted to blobs that can be exported with `writeFile`:
|
||||
`this.file.writeFile` writes file data stored in `Blob` objects to the device.
|
||||
|
||||
From the array of arrays, the SheetJS `aoa_to_sheet` method[^6] generates a
|
||||
worksheet object. The `book_new` and `book_append_sheet` helpers[^7] generate a
|
||||
workbook object. The SheetJS `write` method[^8] with the option `type: "array"`
|
||||
will generate an `ArrayBuffer`, from which a `Blob` can be created:
|
||||
|
||||
```ts
|
||||
/* write a workbook */
|
||||
const wbout: ArrayBuffer = XLSX.write(wb, { bookType: 'xlsx', type: 'array' });
|
||||
let blob = new Blob([wbout], {type: 'application/octet-stream'});
|
||||
/* generate worksheet */
|
||||
const ws: XLSX.WorkSheet = XLSX.utils.aoa_to_sheet(this.data);
|
||||
|
||||
/* generate workbook and add the worksheet */
|
||||
const wb: XLSX.WorkBook = XLSX.utils.book_new();
|
||||
XLSX.utils.book_append_sheet(wb, ws, 'SheetJS');
|

This demo was tested on an Intel Mac on 2023 March 28 with Cordova.
|
||||
The file integration uses `@ionic-native/file` version `5.36.0`.
|
||||
The project was last tested in 2023 September 10. `ionic info` showed:
|
||||
|
||||
The iOS simulator runs iOS 15.5 on an iPhone SE (3rd Generation).
|
||||
- Ionic: `@ionic/angular 7.3.3`, `@ionic/angular-toolkit 9.0.0`
|
||||
- Cordova: `cordova-lib@12.0.1`, `android 12.0.1, ios 7.0.1`
|
||||
|
||||
The Android simulator runs Android 12.0 (S) API 31 on a Pixel 3.
|
||||
The file integration uses `@awesome-cordova-plugins/file` version `6.4.0`.
|
||||
|

|

The app in this demo will display data in a table.
|
||||
|
||||
On load, a [test file](https://sheetjs.com/pres.numbers) will be processed.
|
||||
|
||||
When a document is selected with the file picker, it will be processed and the
|
||||
table will refresh to show the contents.
|
||||
|
||||
"Import Data" will attempt to read `SheetJSIonic.xlsx` from a known location. An
|
||||
alert will display the expected location.
|
||||
|
||||
"Export Data" will attempt to export the table data to `SheetJSIonic.xlsx` in a
|
||||
known location. After writing, an alert will display the location of the file.
|
||||
|
||||
|
||||
### Platform Setup
|
||||
|
||||
0) Disable telemetry as noted in the warning.
|
