Changing Line to Bars for Combo Chart using GAS

Sample data

This is a sample data for this sample script. The column B was created by the normal distribution formula, and the column C was created by multiplying random number for column B.

A, B, C
1.0, 0.0001, 0.0000
1.5, 0.0009, 0.0006
2.0, 0.0044, 0.0037
2.5, 0.0175, 0.0133
3.0, 0.0540, 0.0236
3.5, 0.1296, 0.0533
4.0, 0.2420, 0.0073
4.5, 0.3522, 0.2468
5.0, 0.3990, 0.0843
5.5, 0.3522, 0.3352
6.0, 0.2420, 0.2201
6.5, 0.1296, 0.0607
7.0, 0.0540, 0.0256
7.5, 0.0175, 0.0006

8.5, 0.0009, 0.0005
9.0, 0.0001, 0.0001

Create chart

createChart() creates a chart from data. A chart with 2 lines is created by this method.

Sending E-mail When Spreadsheet was Edited from Outside by Sheet API

This sample script sends an e-mail, when spreadsheet was edited from outside by Sheet API v4. When you use this sample, please create a container bound script with spreadsheet which is edited by Sheet API. And please input your e-mail and run firstly a method of createTrigger(). By this, a trigger is installed as onChange(). After this, edit spreadsheet from outside by Sheet API v4.

When when spreadsheet was edited from outside by Sheet API v4, I used sendEmail() as a sample, because script editor is closed.

File Transfer for Google Drive Without Authorization

Overview

In this article, I would like to introduce how to transfer files for Google Drive under no authorization.

This has also been published here. https://github.com/tanaikech/FileTransfer

Description

When we download and upload files for Google Drive, it usually has to use Drive API. In order to use Drive API, access token is required. If you want to make your friends download and upload files for your Google Drive, the authorization process is to take time. So I proposal this.

Dynamical Nested JSON Objects by Golang

This sample script dynamically creates nested JSON objects.

Script

obj := map[string]interface{}{}
for i := 1; i <= 5; i++ {
    value := map[string]interface{}{
        fmt.Sprintf("B_key%d", i): map[string]interface{}{
            "C_key": "value",
        },
    }
    obj[fmt.Sprintf("A_key%d", i)] = value
}

Result

{
  "A_key1": {
    "B_key1": {
      "C_key": "value"
    }
  },
  "A_key2": {
    "B_key2": {
      "C_key": "value"
    }
  },
  "A_key3": {
    "B_key3": {
      "C_key": "value"
    }
  },
  "A_key4": {
    "B_key4": {
      "C_key": "value"
    }
  },
  "A_key5": {
    "B_key5": {
      "C_key": "value"
    }
  }
}

Changing Slack Status using Google Apps Script

This script changes slack status using GAS. If you want to change it on time you decided, it can be achieved by installing this method as a trigger.

In order to use this, the required scope is users.profile:write.

function setSlackStatus(token, user, status_text, status_emoji) {
  return UrlFetchApp.fetch(
    'https://slack.com/api/users.profile.set',
    {
      method: 'post',
      payload: {
        token: token,
        user: user,
        profile: JSON.stringify({status_text: status_text, status_emoji: status_emoji})
      },
      muteHttpExceptions: true
    }
  ).getContentText();
}

function main() {
  var res = setSlackStatus(
    '### Your access token ###',
    '### User ID ###',
    'sample',
    ':coffee:'
  );
  Logger.log(res)
}

Delete Line Feed Code by DOS and Bash

bash / dos

Input JSON

text.txt :

{
  "values": [
    [
      "a1",
      "b1",
      "c1"
    ],
    [
      "a2",
      "b2",
      "c2"
    ],
    [
      "a3",
      "b3",
      "c3"
    ],
    [
      "a4",
      "b4",
      "c4"
    ],
    [
      "a5",
      "b5",
      "c5"
    ]
  ]
}

Windows DOS

type text.txt | jq -c "."

Linux Bash

$ cat text.txt | jq -c '.'

Output JSON

{"values":[["a1","b1","c1"],["a2","b2","c2"],["a3","b3","c3"],["a4","b4","c4"],["a5","b5","c5"]]}

Updated: CLI Tool - gogauth

golang / Google / CLI

gogauth is a CLI tool to easily retrieve access token for using APIs on Google.

I thought that if the access token can easily retrieve, it may be useful for users who can use various convenience Google APIs. So I created this. Also this can be used for testing sample script like the demo. If this will be helpful for you, I’m glad.

Today, it was updated to v2.0.1. Please check it out. https://github.com/tanaikech/gogauth

OCR using Google Drive API

This is a sample script for OCR using Google Drive API. A text file which converted by OCR can be retrieved by inputting an image file.

In this sample, Python Quickstart is used. The detail information is https://developers.google.com/drive/v3/web/quickstart/python. Please read “Step 1: Turn on the Drive API” and “Step 2: Install the Google Client Library”.
