Updated: Expanding A1Notations using Google Apps Script

Gists

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
  const columnToLetter = column => {
    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 r = a1.length > 1 ? a1[1] : a1[0];
    const [r1, r2] = r.split(":");

Drawing objects on Spreadsheet got to be able to be managed

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());

Retrieving Overwrapped Cells Between 2 Ranges on Google Spreadsheet using Google Apps Script

Gists

This is a sample script for retrieving the overwrapped cells between 2 ranges on Google Spreadsheet using Google Apps Script. Please use this with enabling V8.

const getOverwrappedRanges_ = (rangeList1, rangeList2) => {
  if (
    rangeList1.toString() != "RangeList" ||
    rangeList2.toString() != "RangeList"
  ) {
    throw new Error("Input RangeList object.");
  }

  // Ref: https://stackoverflow.com/a/21231012/7108653
  const columnToLetter = column => {
    let temp,
      letter = "";
    while (column > 0) {
      temp = (column - 1) % 26;
      letter = String.fromCharCode(temp + 65) + letter;
      column = (column - temp - 1) / 26;
    }
    return letter;
  };

  // Expand range1.
  const ar = rangeList1.getRanges().reduce((ar, r) => {
    const startRow1 = r.getRow();
    const endRow1 = startRow1 + r.getNumRows();
    const startColumn1 = r.getColumn();
    const endColumn1 = startColumn1 + r.getNumColumns();
    for (let j = startRow1; j < endRow1; j++) {
      for (let k = startColumn1; k < endColumn1; k++) {
        ar.push(columnToLetter(k) + j);
      }
    }
    return ar;
  }, []);

  // Expand range2.
  const map = rangeList2.getRanges().reduce((m, r) => {
    const startRow2 = r.getRow();
    const endRow2 = startRow2 + r.getNumRows();
    const startColumn2 = r.getColumn();
    const endColumn2 = startColumn2 + r.getNumColumns();
    for (let j = startRow2; j < endRow2; j++) {
      for (let k = startColumn2; k < endColumn2; k++) {
        m.set(columnToLetter(k) + j, null);
      }
    }
    return m;
  }, new Map());

  return ar.filter(e => map.has(e));
};

const main = () => {
  const range1 = ["B3:C7", "D6:E9"]; // Please input range1 as a1Notation.
  const range2 = ["A2:B3", "C7:D10"]; // Please input range2 as a1Notation.

  const sheet = SpreadsheetApp.getActiveSheet();
  const res = getOverwrappedRanges_(
    sheet.getRangeList(range1),
    sheet.getRangeList(range2)
  );
  console.log(res); // <--- ["B3","C7","D7","D8","D9"]
};

  • In this sample script, from the ranges of "B3:C7", "D6:E9" and "A2:B3", "C7:D10", the overwrapped cells are returned. In this case, ["B3","C7","D7","D8","D9"] is returned.

Introduction

V8 engine got to be able to be used at Google Apps Script. By this, I have reported about the process costs with and without using V8. Ref It is considered that knowing the process costs for various methods will be useful for creating the applications with Google Apps Script. Here, I would like to introduce the process costs of each situations under V8. The situations which measured the cost are as follows.

Retrieving Files and Folders without Parents in Google Drive

Gists

This is a sample script for retrieving the files and folders which have no parents in own Google Drive.

When you use this script, please enable Drive API at Advanced Google services.

Sample script

const myFunction = () => {
  const token = ScriptApp.getOAuthToken();
  const fields = decodeURIComponent(
    "nextPageToken,files(name,id,mimeType,parents)"
  );
  const q = decodeURIComponent("'me' in owners and trashed = false");
  let files = [];
  let pageToken = "";
  do {
    const res = UrlFetchApp.fetch(
      `https://www.googleapis.com/drive/v3/files?pageSize=1000&fields=${fields}&q=${q}&pageToken=${pageToken}`,
      { headers: { authorization: `Bearer ${token}` } }
    );
    const obj = JSON.parse(res);
    Array.prototype.push.apply(files, obj.files);
    pageToken = obj.nextPageToken;
  } while (pageToken);
  const result = files.filter(({ parents }) => !parents);
  console.log(result);
};

When you run the script, the files and folders which have no parents in own Google Drive are retrieved.

Updated ggsrun to v174

  • v1.7.4 (March 11, 2020)

    1. Recently, I noticed that new Google Apps Script project of the standalone script type cannot be created by the create method of Drive API. From now, in order to create the standalone Google Apps Script project, only Google Apps Script API is required to be used. Ref By this, I updated ggsrun. So the command for creating new GAS project is not changed.

      • $ ggsrun u -p ###folderId### -f sample.gs -pn sampleGASProjectName

You can check ggsrun at https://github.com/tanaikech/ggsrun.

Drive API cannot create Google Apps Script project no longer

Gists

Today, I noticed that new Google Apps Script project of the standalone script type cannot be created by the method of Files: create in Drive API. From now, in order to manage the Google Apps Script project, only Google Apps Script API is required to be used. By this, the following issues are brought.

  • When the new standalone GAS project is created in the specific folder by uploading the local script, the following flow is required to be run.
    1. Create new standalone GAS project by Apps Script API.
    2. Put the local script to the created GAS project by updating the project with Apps Script API.
    3. Move the GAS project from the root folder to the specific folder using Drive API.

From now, 3 API calls are required to be used like above. By the way, this had been able to be achieved by one API call of the method of files.create in Drive API before.

Simple Script of Resumable Upload with Google Drive API for Python

Gists

This is a simple sample script for achieving the resumable upload to Google Drive using Python. In order to achieve the resumable upload, at first, it is required to retrieve the location, which is the endpoint of upload. The location is included in the response headers. After the location was retrieved, the file can be uploaded to the location URL.

In this sample, a PNG file is uploaded with the resumable upload using a single chunk.
