function getEmails_(q) {
var emails = [];
var threads = GmailApp.search(q);
for (var i in threads) {
var msgs = threads[i].getMessages();
for (var j in msgs) {
emails.push([msgs[j].getBody().replace(/<.*?>/g, '\n')
.replace(/^\s*\n/gm, '').replace(/^\s*/gm, '').replace(/\s*\n/gm, '\n')
]);
}
}
return emails;
}
function appendData_(sheet, array2d) {
sheet.getRange(1, 1).setValues(array2d);
}
function saveEmails() {
var array2d = getEmails_(SEARCH_QUERY);
if (array2d) {
appendData_(SpreadsheetApp.getActiveSpreadsheet().getSheetByName('numberlist'), array2d);
}
markArchivedAsRead ();
}
function markArchivedAsRead() {
var threads = GmailApp.search('label:inbox is:unread to:me subject:importnumberlist');
GmailApp.markThreadsRead(threads);
};
Please, help me to paste table with right dimensions.

Answer 1

Try this one.
Replace getEmails_(q) function
Code#1:
function getEmails_(q) {
var emails = [];
var threads = GmailApp.search(q);
for (var i in threads) {
var msgs = threads[i].getMessages();
for (var j in msgs) {
var arrStr = msgs[j].getBody()
.replace(/<\/tr>/gm, '[/tr]')
.replace(/<\/td>/gm, '[/td]')
.replace(/<.*?>/g, '\n')
.replace(/^\s*\n/gm, '')
.replace(/^\s*/gm, '')
.replace(/\s*\n/gm, '\n')
.split("[/tr]");
var line = [];
for (var i = 0; i < arrStr.length - 1; i++) {
line = arrStr[i].split("[/td]");
line.length -= 1;
emails.push(line);
}
}
}
return emails;
}
Replace appendData_ function
Code#2:
function appendData_(sheet, array2d) {
var h = array2d.length;
var l = array2d[0].length;
sheet.getRange(1, 1, h, l).setValues(array2d);
}
This code converts the html text into 2d array and then paste it into Spreadsheet.
Note 2020-06
Your email may (1) contain several tables or (2) a table with merged cells. In this case, the proposed script may cause an error:
The number of columns in the data does not match the number of columns
in the range
In this situation, you'll need to create another function to parse the message body. I suggest you see the HTML-code of your message and inspect it in Gmail:
Right Click > Instect
or [Ctrl]+[Shift]+[I]
The other approach in this situation is to paste data "as is", use sample function to convert any 2d array into rectangular:
function convert2ArrayToRectangular_(array2d)
{
// get max width
var res = [];
var w = 0;
for (var i = 0; i < array2d.length; i++)
{
if (array2d[i].length > w) {w = array2d[i].length;}
}
var row = [];
for (var i = 0; i < array2d.length; i++)
{
row = array2d[i];
if(array2d[i].length < w)
{
for (var ii = array2d[i].length; ii < w; ii++)
{
row.push('');
}
}
res.push(row);
}
return res;
}
Sample usage:
function test_get_email() {
var q = 'Test_table_to_sheets';
var array2d = getEmails_(q);
var sheet = SpreadsheetApp.openById('1BKkd5LwBYyGoi2um-S3pTCBKrUEko34m9vJu94K8uOQ').getSheetByName('Test_table_to_sheets2');
appendData_(sheet, convert2ArrayToRectangular_(array2d));
}
