# Tutorial

SheetJS presents a simple JS interface that works with "Array of Arrays" and
"Array of JS Objects".  The API functions are building blocks that should be
combined with other JS APIs to solve problems.

The discussion focuses on the problem solving mindset.  API details are covered
in other parts of the documentation.

The goal of this example is to generate a XLSX workbook of US President names
and birthdays.  [Click here](#live-demo) to jump to the live demo. The sequence
diagram below shows the process:

```


## Acquire Data

### Raw Data

[The raw data is available in JSON form](https://theunitedstates.io/congress-legislators/executive.json).
For convenience, it has been [mirrored here](https://sheetjs.com/data/executive.json)

Acquiring the data is straightforward with `fetch`:

```js
const url = "https://sheetjs.com/data/executive.json";
const raw_data = await (await fetch(url)).json();
```

The raw data is an Array of objects. This is the data for John Adams:

```js
{
  "id": { /* (data omitted) */ },
  "name": {
    "first": "John",          // <-- first name
    "last": "Adams"           // <-- last name
  },
  "bio": {
    "birthday": "1735-10-19", // <-- birthday
    "gender": "M"
  },
  "terms": [
    { "type": "viceprez", /* (other fields omitted) */ },
    { "type": "viceprez", /* (other fields omitted) */ },
    { "type": "prez", /* (other fields omitted) */ }
  ]
}
```

### Filtering for Presidents

The dataset includes Aaron Burr, a Vice President who was never President!

`Array#filter` creates a new array with the desired rows.  A President served
at least one term with `type` set to `"prez"`.  To test if a particular row has
at least one `"prez"` term, `Array#some` is another native JS function.  The
complete filter would be:

```js
const prez = raw_data.filter(row => row.terms.some(term => term.type === "prez"));
```

### Sorting by First Term

The dataset is sorted in chronological order by the first presidential or vice
presidential term.  The Vice President and President in a given term are sorted
alphabetically. Joe Biden and Barack Obama were Vice President and President
respectively in 2009. Since "Biden" is lexicographically before "Obama", Biden's
data point appears first. The goal is to sort the presidents in order of their
presidential term.

The first step is adding the first presidential term start date to the dataset.
`Array#find` will find the first value in an array that matches a criterion.
The following code looks at each president and creates a `"start"` property that
represents the start of the first presidential term.

```js
prez.forEach(prez => prez.start = prez.terms.find(term => term.type === "prez").start);
```

`Array#sort` will sort the array. Since the `start` properties are strings, the
recommended approach is to use `String#localeCompare` to compare strings:

```js
prez.sort((l,r) => l.start.localeCompare(r.start));
```

### Reshaping the Array

For this example, the name will be the first name combined with the last name
(`row.name.first + " " + row.name.last`) and the birthday will be available at
`row.bio.birthday`.  Using `Array#map`, the dataset can be massaged in one call:

```js
const rows = prez.map(row => ({
  name: row.name.first + " " + row.name.last,
  birthday: row.bio.birthday
}));
```

The result is an array of "simple" objects with no nesting:

```js
[
  { name: "George Washington", birthday: "1732-02-22" },
  { name: "John Adams", birthday: "1735-10-19" },
  // ... one row per President
]
```

## Create a Workbook

With the cleaned dataset, `XLSX.utils.json_to_sheet` generates a worksheet:

```js
const worksheet = XLSX.utils.json_to_sheet(rows);
```

`XLSX.utils.book_new` creates a new workbook and `XLSX.utils.book_append_sheet`
appends a worksheet to the workbook. The new worksheet will be called "Dates":

```js
const workbook = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(workbook, worksheet, "Dates");
```

## Clean up Workbook

The data is in the workbook and can be exported.

![Rough export](pathname:///example/rough.png)

There are multiple opportunities for improvement: the headers can be renamed and
the column widths can be adjusted.  [SheetJS Pro](https://sheetjs.com/pro) offers
additional styling options like cell styling and frozen rows.

<details><summary><b>Changing Header Names</b> (click to show)</summary>

By default, `json_to_sheet` creates a worksheet with a header row. In this case,
the headers come from the JS object keys: "name" and "birthday".

The headers are in cells `A1` and `B1`.  `XLSX.utils.sheet_add_aoa` can write
text values to the existing worksheet starting at cell `A1`:

```js
XLSX.utils.sheet_add_aoa(worksheet, [["Name", "Birthday"]], { origin: "A1" });
```

</details>

<details><summary><b>Changing Column Widths</b> (click to show)</summary>

Some of the names are longer than the default column width.  Column widths are
set by setting the `"!cols"` worksheet property.

The following line sets the width of column A to approximately 10 characters:

```js
worksheet["!cols"] = [ { wch: 10 } ]; // set column A width to 10 characters
```

One `Array#reduce` call over `rows` can calculate the maximum width:

```js
const max_width = rows.reduce((w, r) => Math.max(w, r.name.length), 10);
worksheet["!cols"] = [ { wch: max_width } ];
```

</details>

After cleanup, the generated workbook looks like the screenshot below:

![Final export](pathname:///example/final.png)

## Export a File

`XLSX.writeFile` creates a spreadsheet file and tries to write it to the system.
In the browser, it will try to prompt the user to download the file.  In NodeJS,
it will write to the local directory.

```js
XLSX.writeFile(workbook, "Presidents.xlsx", { compression: true });
```

## Live Demo

This demo runs in the web browser!  Click "Click to Generate File!" and the
browser should try to create `Presidents.xlsx`

```jsx live
function Presidents() { return ( <button onClick={async () => {
  /* fetch JSON data and parse */
  const url = "https://sheetjs.com/data/executive.json";
  const raw_data = await (await fetch(url)).json();

  /* filter for the Presidents */
  const prez = raw_data.filter(row => row.terms.some(term => term.type === "prez"));

  /* sort by first presidential term */
  prez.forEach(prez => prez.start = prez.terms.find(term => term.type === "prez").start);
  prez.sort((l,r) => l.start.localeCompare(r.start));

  /* flatten objects */
  const rows = prez.map(row => ({
    name: row.name.first + " " + row.name.last,
    birthday: row.bio.birthday
  }));

  /* generate worksheet and workbook */
  const worksheet = XLSX.utils.json_to_sheet(rows);
  const workbook = XLSX.utils.book_new();
  XLSX.utils.book_append_sheet(workbook, worksheet, "Dates");

  /* fix headers */
  XLSX.utils.sheet_add_aoa(worksheet, [["Name", "Birthday"]], { origin: "A1" });

  /* calculate column width */
  const max_width = rows.reduce((w, r) => Math.max(w, r.name.length), 10);
  worksheet["!cols"] = [ { wch: max_width } ];

  /* create an XLSX file and try to save to Presidents.xlsx */
  XLSX.writeFile(workbook, "Presidents.xlsx", { compression: true });
}}><b>Click to Generate file!</b></button> ); }
```

The Android demo has been tested in Windows 10 and in macOS.

:::

Test the app in the Android simulator:

```bash
npm run android
```

After clicking "Press to Export", the app will show an alert with the location
to the generated file.

In the Android simulator, pulling the file requires additional steps.  This
command will pull a Base64-encoded string from the simulator:

```bash
adb exec-out run-as com.sheetjspres base64 files/Presidents.xlsx > pres.b64
```

Decoding the file requires an OS-specific command:

This command generates `Presidents.xlsx` which can be opened.

:::info Device Testing

["Running on Device"](https://reactnative.dev/docs/running-on-device) in the

`Presidents.xlsx` will be copied to the `Downloads` folder. The file is visible
in the Files app and can be opened with the Google Sheets app.

  <TabItem value="ios" label="iOS">

:::caution

This demo runs in iOS and requires a Macintosh computer with Xcode installed.

:::info Device Testing

["Running on Device"](https://reactnative.dev/docs/running-on-device) in the
React Native docs covers device configuration.

The `UIFileSharingEnabled` and `LSSupportsOpeningDocumentsInPlace` entitlements
are required for iOS to show the generated files in the "Files" app.

The highlighted lines should be added to the iOS project `Info.plist` just
before the last `</dict>` tag:

```xml title="ios/SheetJSPres/Info.plist"
	<key>UIViewControllerBasedStatusBarAppearance</key>

After adding the settings and rebuilding the app, the file will be visible in
the "Files" app.  Under "On My iPhone", there will be a folder `SheetJSPres`.
Within the folder there will be a file named `Presidents`. Touch the file to
