# Overview
This is a Node.js module to manage the tables on Google Document using Google Docs API.
# Description
Google Docs API has been released. When I used this API, I found that it is very difficult for me to manage the tables on Google Document using Google Docs API. Although I checked [the official document](https://developers.google.com/docs/api/how-tos/tables), unfortunately, I thought that it's very difficult for me. So in order to easily manage the tables on Google Document, I created this library.
## Features
- All values can be retrieved from the table on Google Document.
- Values can be put to the table.
- Delete table, rows and columns of the table.
- New table can be created by including values.
- Append rows to the table by including values.
- Replace texts with images.
- The image data can be retrieved from URL.
- The image data can be uploaded from the local PC.
## Languages
I manages the tables on Google Document using several languages. So I created the libraries for 4 languages which are golang, node.js and python. Google Apps Script has Class DocumentApp. So I has never created the GAS library yet.
- [go-gdoctableapp](https://github.com/tanaikech/go-gdoctableapp)
- [node-gdoctableapp](https://github.com/tanaikech/node-gdoctableapp)
- [gdoctableapppy](https://github.com/tanaikech/gdoctableapppy)
- [google-docs-table-factory](https://github.com/gumatias/google-docs-table-factory) by gumatias
# Install
```bash
$ npm install --save-dev gdoctableapp
```
or
```bash
$ npm install --global gdoctableapp
```
You can also see this module at [https://www.npmjs.com/package/gdoctableapp](https://www.npmjs.com/package/gdoctableapp).

## Response
This library returns the following value.
```javascript
{
tables: []tables,
values: []values,
responseFromAPIs: []responses,
libraryVersion: version
}
```
- When `GetTables()` is used, you can see the values with `tables`.
- When `GetValues()` is used, you can see the values with `values`.
- When other methods are used and the option of `showAPIResponse` is `true`, you can see the responses from APIs which were used for the method. And also, you can know the number of APIs, which were used for the method, by the length of array of `responseFromAPIs`.
# Usage
About the authorization, please check the section of [Authorization](#authorization). In order to use this library, it is required to confirm that [the Quickstart](https://developers.google.com/docs/api/quickstart/nodejs) works fine.
## Scope
In this library, using the scope of `https://www.googleapis.com/auth/documents` is recommended. When the method of `ReplaceTextsToImagesByFile` is used, also please add `https://www.googleapis.com/auth/drive`.
## 1. GetTables
Get all tables from Document. All values, table index and table position are retrieved.
### Sample script
This sample script retrieves all tables from the Google Document of document ID.
```javascript
const resource = {
auth: auth,
documentId: documentId
// showAPIResponse: true // When showAPIResponse is true, the responses from Docs API can be seen.
};
gdoctableapp.GetTables(resource, function(err, res) {
if (err) {
console.log(err);
return;
}
console.log(JSON.stringify(res.tables));
});
```
- `documentId`: Document ID.
- `auth`: oAuth2Client for using Docs API. Please check the section of [Authorization](#authorization).
- `showAPIResponse`: When `showAPIResponse: true` is used to `resource`, the responses from Docs API can be seen. The default value is `false`. **This option can be used for all methods.**
## 2. GetValues
Get values from a table from Document. All values are retrieved.
### Sample script
This sample script retrieves the values from 1st table in Google Document. You can see the retrieved values as `[][]string`. Because when the values are retrieved by Docs API, all values are automatically converted to the string data.
```javascript
const resource = {
auth: auth,
documentId: "###",
tableIndex: 0
};
gdoctableapp.GetValues(resource, function(err, res) {
if (err) {
console.log(err);
return;
}
console.log(res.values); // You can see the retrieved values like this.
});
```
- `documentId`: Document ID.
- `tableIndex`: Table index. If you want to use the 3rd table in Google Document. It's 2. The start number of index is 0.
- `auth`: oAuth2Client for using Docs API. Please check the section of [Authorization](#authorization).
- `showAPIResponse`: When `showAPIResponse: true` is used to `resource`, the responses from Docs API can be seen. The default value is `false`.
## 3. SetValues 1
There are 2 patterns for putting values to the table. In this section, set values to the table with 2 dimensional array. When the rows and columns of values which are put are over those of the table, this method can automatically expand the rows and columns.
### Sample script
This sample script puts the values to the first table in Google Document.
```javascript
const resource = {
auth: auth,
documentId: "###",
tableIndex: 0,
values: [
["a1", "b1"],
["a2", "b2"],
["a3", "b3", "c3"]
]
};
gdoctableapp.SetValues(resource, function(err, res) {
if (err) {
console.log(err);
return;
}
console.log(res); // You can see the retrieved responses from Docs API.
});
```
- `documentId`: Document ID.
- `tableIndex`: Table index. If you want to use the 3rd table in Google Document. It's 2. The start number of index is 0.
- `auth`: oAuth2Client for using Docs API. Please check the section of [Authorization](#authorization).
- `values`: `[][]string`
- `showAPIResponse`: When `showAPIResponse: true` is used to `resource`, the responses from Docs API can be seen. The default value is `false`.
### Result
When above script is run, the following result is obtained.
#### From:
#### To:
## 4. SetValues 2
There are 2 patterns for putting values to the table. In this section, set values to a table with an object. In this method, you can set the values using the range. When the rows and columns of values which are put are over those of the table, this method can automatically expand the rows and columns.
### Sample script
This script puts the values with the range to the first table in Google Document.
```javascript
const resource = {
auth: auth,
documentId: "###",
tableIndex: 0,
values: [
{
values: [["A1"], ["A2", "B2", "c2", "d2"], ["A3"]],
range: { startRowIndex: 0, startColumnIndex: 0 }
},
{
values: [["B1", "C1"]],
range: { startRowIndex: 0, startColumnIndex: 1 }
}
]
};
gdoctableapp.SetValues(resource, function(err, res) {
if (err) {
console.log(err);
return;
}
console.log(res); // You can see the retrieved responses from Docs API.
});
```
- `documentId`: Document ID.
- `tableIndex`: Table index. If you want to use the 3rd table in Google Document. It's 2. The start number of index is 0.
- `auth`: oAuth2Client for using Docs API. Please check the section of [Authorization](#authorization).
- `range.startRowIndex` of `values`: Row index of `values[0][0]`.
- `range.startColumnIndex` of `values`: Column index of `values[0][0]`.
- `values` : Values you want to put.
- `showAPIResponse`: When `showAPIResponse: true` is used to `resource`, the responses from Docs API can be seen. The default value is `false`.
For example, when the row, column indexes and values are 1, 2 and "value", respectively, "value" is put to "C3".
### Result
When above script is run, the following result is obtained.
#### From:
#### To:
## 5. DeleteTable
### Sample script
This script deletes the first table in Google Document.
```javascript
const resource = {
auth: auth,
documentId: "###",
tableIndex: 0
};
gdoctableapp.DeleteTable(resource, function(err, res) {
if (err) {
console.log(err);
return;
}
console.log(res.result); // You can see the retrieved responses from Docs API.
});
```
- `documentId`: Document ID.
- `tableIndex`: Table index. If you want to use the 3rd table in Google Document. It's 2. The start number of index is 0.
- `auth`: oAuth2Client for using Docs API. Please check the section of [Authorization](#authorization).
- `showAPIResponse`: When `showAPIResponse: true` is used to `resource`, the responses from Docs API can be seen. The default value is `false`.
## 6. DeleteRowsAndColumns
### Sample script
This script deletes rows of indexes of 3, 1 and 2 of the first table in Google Document. And also this script deletes columns of indexes of 2, 1 and 3.
```javascript
const resource = {
auth: auth,
documentId: "###",
tableIndex: 0,
deleteRows: [3, 1, 2], // Start index is 0.
deleteColumns: [2, 1, 3] // Start index is 0.
};
gdoctableapp.DeleteRowsAndColumns(resource, function(err, res) {
if (err) {
console.log(err);
return;
}
console.log(res); // You can see the retrieved responses from Docs API.
});
```
- `documentId`: Document ID.
- `tableIndex`: Table index. If you want to use the 3rd table in Google Document. It's 2. The start number of index is 0.
- `auth`: oAuth2Client for using Docs API. Please check the section of [Authorization](#authorization).
- `deleteRows` : Indexes of rows you want to delete.
- `deleteColumns` : Indexes of columns you want to delete.
- `showAPIResponse`: When `showAPIResponse: true` is used to `resource`, the responses from Docs API can be seen. The default value is `false`.
## 7. CreateTable
### Sample script
This script creates new table to the top of Google Document, and the cells of the table have values.
```javascript
const resource = {
auth: auth,
documentId: "###",
rows: 3,
columns: 5,
createIndex: 1,
// append: true, // When this is used instead of "Index", new table is created to the end of Document.
values: [
["a1", "b1"],
["a2", "b2"],
["a3", "b3", "c3"]
]
};
gdoctableapp.CreateTable(resource, function(err, res) {
if (err) {
console.log(err);
return;
}
console.log(res); // You can see the retrieved responses from Docs API.
});
```
- `documentId`: Document ID.
- `auth`: oAuth2Client for using Docs API. Please check the section of [Authorization](#authorization).
- `rows` : Number of rows of new table.
- `columns` : Number of columns of new table.
- `createIndex` : Index of Document for putting new table. For example, `1` is the top of Document.
- `append` : When `append` is `true` instead of `createIndex`, the new table is created to the end of Google Document.
- `values` : If you want to put the values when new table is created, please use this.
- `showAPIResponse`: When `showAPIResponse: true` is used to `resource`, the responses from Docs API can be seen. The default value is `false`.
### Result
When above script is run, the following result is obtained. In this case, the new table is created to the top of Google Document.
## 8. AppendRow
### Sample script
This sample script appends the values to the first table of Google Document.
```javascript
const resource = {
auth: auth,
documentId: "###",
tableIndex: 0,
values: [
["a1", "b1", "c1", 1, "", 2],
["a2", "b2", "c2", 1, "", 2]
]
};
gdoctableapp.AppendRow(resource, function(err, res) {
if (err) {
console.log(err);
return;
}
console.log(res); // You can see the retrieved responses from Docs API.
});
```
- `documentId`: Document ID.
- `tableIndex`: Table index. If you want to use the 3rd table in Google Document. It's 2. The start number of index is 0.
- `auth`: oAuth2Client for using Docs API. Please check the section of [Authorization](#authorization).
- `values` : Values you want to append to the existing table.
- `showAPIResponse`: When `showAPIResponse: true` is used to `resource`, the responses from Docs API can be seen. The default value is `false`.
### Result
When above script is run, the following result is obtained. In this case, the values are put to the last row. And you can see that 3 columns are automatically added when the script is run.

## 9. ReplaceTextsToImages
### Sample script
In this sample, the texts `{{sample}}` in all tables are replaced with the image. In this case, you can use the image from an URL or a file on local PC.
```javascript
const resource = {
auth: auth,
documentId: "###",
showAPIResponse: false, // default is false
tableOnly: true, // default is false
searchText: "{{sample}}",
imageWidth: 50,
imageHeight: 50,
replaceImageURL: "https://###/sample.png"
// replaceImageFilePath: "./sample.png"
};
gdoctableapp.ReplaceTextsToImages(resource, function(err, res) {
if (err) {
console.log(err);
return;
}
console.log(JSON.stringify(res));
});
```
- `documentId`: Document ID.
- `auth`: oAuth2Client for using Docs API. Please check the section of [Authorization](#authorization).
- `searchText`: Search text. This text is replaced with image.
- `replaceImageURL`: URL of the image. When this property is used, the image is retrieved from the URL, and the retrieved image is used.
- `replaceImageFilePath`: File path of the image. When this property is used, the image is retrieved from the file on local PC, and the retrieved image is used.
- `imageWidth`: Width of the put image.
- `imageHeight`: Height of the put image.
- `tableOnly`: When this is `true`, only texts in the table are replaced with image. When this is `false`, the texts in the body are replaced.
- `showAPIResponse`: When `showAPIResponse: true` is used to `resource`, the responses from Docs API can be seen. The default value is `false`.
### Note
- The flow for replacing the text with the image on the local PC.
1. Upload the image from local PC to Google Drive.
2. Publicly share the image file. - The time for sharing is several seconds. The file is delete after the image is put.
3. Put the image using the URL of the publicly shared file.
4. Delete the image. - Even when the image is delete from Google Drive, the put image on Google Document is not deleted.
- About `imageWidth` and `imageHeight`
> [**objectSize**](https://developers.google.com/docs/api/reference/rest/v1/documents/request#insertinlineimagerequest): The size that the image should appear as in the document. This property is optional and the final size of the image in the document is determined by the following rules: _ If neither width nor height is specified, then a default size of the image is calculated based on its resolution. _ If one dimension is specified then the other dimension is calculated to preserve the aspect ratio of the image. \* If both width and height are specified, the image is scaled to fit within the provided dimensions while maintaining its aspect ratio.
### Result
When above script is run, the following result is obtained.
#### From:
#### To:
The image of `https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-logo.png` was used as the sample image.
When `tableOnly` is `false`, the following result is retrieved.
# Authorization
There are 2 patterns for using this library.
## 1. Use OAuth2
Document of OAuth2 is [here](https://developers.google.com/identity/protocols/OAuth2).
### Sample script
In this sample script, the authorization process uses [the Quickstart for Node.js](https://developers.google.com/docs/api/quickstart/nodejs). You can see the detail information at there.
```javascript
const fs = require("fs");
const readline = require("readline");
const { google } = require("googleapis");
// If modifying these scopes, delete token.json.
const SCOPES = ["https://www.googleapis.com/auth/documents"];
// The file token.json stores the user's access and refresh tokens, and is
// created automatically when the authorization flow completes for the first
// time.
const TOKEN_PATH = "token.json";
// Load client secrets from a local file.
fs.readFile("credentials.json", (err, content) => {
if (err) return console.log("Error loading client secret file:", err);
// Authorize a client with credentials, then call the Google Drive API.
authorize(JSON.parse(content), doGdoctableapp);
});
/**
* Create an OAuth2 client with the given credentials, and then execute the
* given callback function.
* @param {Object} credentials The authorization client credentials.
* @param {function} callback The callback to call with the authorized client.
*/
function authorize(credentials, callback) {
const { client_secret, client_id, redirect_uris } = credentials.installed;
const oAuth2Client = new google.auth.OAuth2(
client_id,
client_secret,
redirect_uris[0]
);
// Check if we have previously stored a token.
fs.readFile(TOKEN_PATH, (err, token) => {
if (err) return getAccessToken(oAuth2Client, callback);
oAuth2Client.setCredentials(JSON.parse(token));
callback(oAuth2Client);
});
}
/**
* Get and store new token after prompting for user authorization, and then
* execute the given callback with the authorized OAuth2 client.
* @param {google.auth.OAuth2} oAuth2Client The OAuth2 client to get token for.
* @param {getEventsCallback} callback The callback for the authorized client.
*/
function getAccessToken(oAuth2Client, callback) {
const authUrl = oAuth2Client.generateAuthUrl({
access_type: "offline",
scope: SCOPES
});
console.log("Authorize this app by visiting this url:", authUrl);
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
rl.question("Enter the code from that page here: ", code => {
rl.close();
oAuth2Client.getToken(code, (err, token) => {
if (err) return console.error("Error retrieving access token", err);
oAuth2Client.setCredentials(token);
// Store the token to disk for later program executions
fs.writeFile(TOKEN_PATH, JSON.stringify(token), err => {
if (err) console.error(err);
console.log("Token stored to", TOKEN_PATH);
});
callback(oAuth2Client);
});
});
}
/**
* Using gdoctableapp.
*/
function doGdoctableapp(auth) {
const gdoctableapp = require("gdoctableapp");
const resource = {
auth: auth,
documentId: "###",
tableIndex: 0
};
gdoctableapp.GetValues(resource, function(err, res) {
if (err) {
console.log(err);
return;
}
console.log(res.values); // You can see the retrieved values like this.
});
}
```
## 2. Use Service account
Document of Service account is [here](https://developers.google.com/identity/protocols/OAuth2ServiceAccount). When you use Service account, please share Google Document with the email of Service account.
### Sample script
```javascript
const { google } = require("googleapis");
const gdoctableapp = require("gdoctableapp");
const key = require("### json file including public/private key pair ###");
const jwtClient = new google.auth.JWT(
key.client_email,
null,
key.private_key,
["https://www.googleapis.com/auth/documents"],
null
);
const resource = {
auth: jwtClient,
documentId: "###",
tableIndex: 0
};
gdoctableapp.GetValues(resource, function(err, res) {
if (err) {
console.log(err);
return;
}
console.log(res.values); // You can see the retrieved values like this.
});
```
# Limitations
- In the current stage, unfortunately, `tableCellStyle` cannot be modified by Google Docs API. By this, the formats of cells cannot be modified. About this, I have posted as [Feature Request](https://issuetracker.google.com/issues/135136221).
