Google spreadsheet: Download all the sheets at once - google-sheets

Question

When working with google spreadsheet, how to download all the sheets at once?
I want to use the option:
Comma-separated values
But it only download the current sheet, how to get them all?

Answer 1

For anyone who navigates to this question, trying to download all the tabs in their Google spreadsheets as CSV files at once, even in 2021, there does not seem to be a GUI button to do this. At least I could not see anything. The answer by #Amit Agarwal does well, to get all sheets, but if your file has comma-delimited data in cells, then data could get mangled.
I took Amit's approach https://stackoverflow.com/a/28711961 and combined it with Michael Derazon and Aaron Davis's approach here https://gist.github.com/mrkrndvs/a2c8ff518b16e9188338cb809e06ccf1 to dump all the tabs of a chosen Google spreadsheet into a folder in Google Drive. You can then just download the folder with a single click.
The following is Google script, not exactly a Javascript, and you would have to copy-paste this in https://script.google.com/ login with your Google id, and then create a project and then create a script app, and save and execute this.
// https://stackoverflow.com/a/28711961
function export_sheets_as_csv_to_folder() {
// Sheet id is in URL https://docs.google.com/spreadsheets/d/YOUR_SHEET_ID/edit#gid=IGNORE
var ss = SpreadsheetApp.openById('YOUR_SHEET_ID');
var sheets = ss.getSheets();
if (sheets === undefined || sheets.length === 0) {
return;
}
var passThroughFolder = DriveApp.createFolder('YOUR_PREFERRED_FOLDER_NAME_IN_DRIVE');
for (var s in sheets) {
var csv = convertRangeToCsvFile_(sheets[s])
passThroughFolder.createFile(sheets[s].getName() + ".csv", csv);
}
}
// https://gist.github.com/mrkrndvs/a2c8ff518b16e9188338cb809e06ccf1
function convertRangeToCsvFile_(sheet) {
// get available data range in the spreadsheet
var activeRange = sheet.getDataRange();
try {
var data = activeRange.getValues();
var csvFile = undefined;
// loop through the data in the range and build a string with the csv data
if (data.length > 1) {
var csv = "";
for (var row = 0; row < data.length; row++) {
for (var col = 0; col < data[row].length; col++) {
if (data[row][col].toString().indexOf(",") != -1) {
data[row][col] = "\"" + data[row][col] + "\"";
}
}
// join each row's columns
// add a carriage return to end of each row, except for the last one
if (row < data.length-1) {
csv += data[row].join(",") + "\r\n";
}
else {
csv += data[row];
}
}
csvFile = csv;
}
return csvFile;
}
catch(err) {
Logger.log(err);
Browser.msgBox(err);
}
}

Answer 2

After clicking download > pdf, select export > worksheet (instead of current sheet which is the default)

Answer 3

You can use Google Scripts to save all the sheets of a spreadsheet into separate files.
function myFunction() {
var ss = SpreadsheetApp.openById(SHEET_ID);
var sheets = ss.getSheets();
for (var s in sheets) {
var csv = "";
var data = sheets[s].getDataRange().getValues();
for (d in data) {
csv += data[d].join(",") + "\n";
}
DriveApp.createFile(sheets[s].getName() + ".csv", csv);
}
}

Answer 4

the answer from #Soham works amazingly but it doesn't handle multiline values. It would be an easy fix just to add more checks to character \n along with , but I took the liberty to rewrite the function using map (and string.includes) so it is more concise.
function convertRangeToCsvFile_(sheet) {
return sheet.getDataRange().getValues()
.map(row => row.map(value => value.toString())
.map(value => (value.includes("\n") || value.includes(",")) ? "\"" + value + "\"" : value)
.join(','))
.join('\n')
}

Answer 5

A slight variation on this that uses a zip instead of a folder to contain the sheets and does some modernizing of the great work done by keychera and Soham's answer.
You can use this as a bound script and it will add a menu item to the extensions menu:
// Code.gs
function exportSheetsToDrive() {
const ss = SpreadsheetApp.getActiveSpreadsheet();
const sheets = ss.getSheets();
if (sheets === undefined || sheets.length === 0) {
return;
}
const now = new Date();
const csvBlobs = sheets.map((sheet) => {
const name = sheet.getName();
const csv = convertSheetToCsv(sheet);
Logger.log({ name, length: csv.length });
return Utilities.newBlob(csv, MimeType.CSV, `${name}.csv`)
});
const zipName = `export_${ss.getName()}_${now.toISOString()}.zip`;
const zip = Utilities.zip(csvBlobs, zipName);
DriveApp.createFile(zip);
}
function convertSheetToCsv(sheet) {
return sheet
.getDataRange()
.getValues()
.map((row) =>
row
.map((value) => value.toString())
.map((value) =>
value.includes("\n") || value.includes(",")
? '"' + value + '"'
: value
)
.join(",")
)
.join("\n");
}
and
// Menu.gs
function onOpen(e) {
const menu = SpreadsheetApp.getUi().createAddonMenu();
menu
.addItem('Export all sheets as CSV to Drive', 'exportSheetsToDrive')
.addToUi();
}
function onInstall(e) {
onOpen(e);
}
