tanaike - Google Apps Script, Gemini API, and Developer Tips

FilesApp was updated to v1.1.0.

1. Shared drive got to be able to be used. From the version 1.1.0, the following modification was added.
   1. V8 is used.
   2. As the default setting, the file list is retrieved from both your Google Drive and the shared drive.
      • By this, for example, when the folder ID in the shared Drive is used to ### of const res = FilesApp.createTree("###"), the folder tree of the shared Drive is retrieved, if you have the shared Drive.

And also, FilesApp was updated to v1.1.1.

These are the sample scripts for hiding and deleting rows and columns on Google Spreadsheet using Google Apps Script. I sometimes see the questions for hiding and deleting rows and columns on Spreadsheet at Stackoverflow. So here, I would like to introduce the sample scripts for this.

In this case, when the process costs of the scripts created by using Spreadsheet service and Sheets API are compared, the cost of script created by Sheets API is much lower than that of script created by Spreadsheet service. So when the rows and columns of your Spreadsheet is large and you can use Sheets API, I recommend to use Sheets API.

Overview

When // in template literal is used in a HTML file in script editor, it is used as a comment start.

const sample = `//`;

For example, when above script is used in a HTML file at the script editor, ;" of const sample =`//`; is used as the comment.

Description

I would like to explain about this bug using the following sample flow.

Flow

1. Create new Spreadsheet and open the script editor. In this explanation, please use the container-bound script.

This is a sample script for retrieving the direct links of all sheets from the URL like https://docs.google.com/spreadsheets/d/e/2PACX-###/pubhtml of the web published Google Spreadsheet. This sample script can be used for the following situation.

1. The Spreadsheet is published to Web and the URL like https://docs.google.com/spreadsheets/d/e/2PACX-###/pubhtml is known
2. You are not the owner of Google Spreadsheet.
3. You don’t know the Spreadsheet ID and Sheet IDs.

Under above situation, unfortunately, the direct links of each sheet cannot be directly retrieved. I think that this is the specification of Google side. So in this post, I would like to introduce a workaround for retrieving the direct links of each sheet under above situation.

goris is a CLI tool to search for images with Google Reverse Image Search.

Today, it was updated to v2.0.0. Please check it out. https://github.com/tanaikech/goris

• v2.0.0 (April 23, 2020)

  1. The specification for running the reverse image search was changed at Google side. By this, this application was also changed.

This is a sample flow for updating a file with the resumable upload using Drive API.

Sample situation:

In this answer, as a sample situation, it supposes that a text file in Google Drive is updated by the resumable upload with the multiple chunks. And as the method for requesting, I use the curl command.

I prepared 2 files for 2 chunks. As the test situation, the 2 chunks of 262,144 bytes and 37,856 bytes are uploaded. So total upload size is 300,000 bytes. Those filenames are data1.txt and data2.txt, respectively.

Description

When V8 is enabled, Array.apply has the limitation for the number of elements. When it is over the limitation, an error like RangeError: Maximum call stack size exceeded occurs, while the issue didn’t occur when V8 is disabled. In this case, this issue occurs at both Google Apps Script and Javascript. So please be careful this.

Sample situation

For example, when Array.prototype.push.apply is used for combining the arrays because the process cost of Array.prototype.push.apply is lowest of 3 patterns of Array.prototype.push.apply, Spread syntax and concat, please be careful above issue. Ref

FetchApp was updated to v1.0.1.

• v1.0.1 (April 13, 2020)

  1. When V8 runtime is enabled, it was found that an error occurred. So this bug was removed.

This sample script is for expanding a1Notations using Google Apps Script. This was updated from this sample script.

Sample script

function expandA1Notations_(a1Notations, maxRow, maxColumn) {
  maxRow = maxRow || "1000";
  maxColumn = maxColumn || "Z";

  // Ref: https://stackoverflow.com/a/21231012/7108653

    let temp,
      letter = "";
    while (column > 0) {
      temp = (column - 1) % 26;
      letter = String.fromCharCode(temp + 65) + letter;
      column = (column - temp - 1) / 26;
    }
    return letter;
  };
  const letterToColumn = letter => {
    let column = 0,
      length = letter.length;
    for (let i = 0; i < length; i++) {
      column += (letter.charCodeAt(i) - 64) * Math.pow(26, length - i - 1);
    }
    return column;
  };

    }
    const obj = {
      startRowIndex: Number(rr[0][2]),
      endRowIndex: rr.length == 1 ? Number(rr[0][2]) + 1 : Number(rr[1][2]) + 1,
      startColumnIndex: letterToColumn(rr[0][1]),
      endColumnIndex:
        rr.length == 1
          ? letterToColumn(rr[0][1]) + 1
          : letterToColumn(rr[1][1]) + 1
    };
    let temp = [];
    for (let i = obj.startRowIndex; i < obj.endRowIndex; i++) {
      for (let j = obj.startColumnIndex; j < obj.endColumnIndex; j++) {
        temp.push(columnToLetter(j) + i);

// When you use this script, please run main().
function main() {
  const a1Notations = ["A1:E3", "B10:W13", "EZ5:FA8", "AAA1:AAB3"];
  const res = expandA1Notations_(a1Notations);
  console.log(res);

The drawing objects on Google Spreadsheet got to be able to be managed by the update at April 2, 2020. Ref

By this update, we can assign the function to the drawing objects and remove the drawing objects. The following sample is for removing the drawing objects on the active sheet. Ref

SpreadsheetApp.getActiveSheet()
  .getDrawings()
  .forEach(e => e.remove());
