Google Sheets API: insert formatted text - node.js

Question

I am trying to insert bolded text into Google Spreadsheet. I have the following NodeJS code that inserts the text successfully.
var body = {
data: [{
range: 'M2:M3',
values: [["value1"],["value2"]]
}],
valueInputOption: 'USER_ENTERED',
};
var sheets = google.sheets('v4');
sheets.spreadsheets.values.batchUpdate({
auth: auth,
spreadsheetId: SPREADSHEET_ID,
resource: body
}, function(err, response) {
if (err) {
console.log('The API returned an error: ' + err);
return;
}
});
I looked up and found that in order to change the text format to bold, the following code needs to be used.
requests: [
{
"format": {
"textFormat": {
"bold": true
}
}
}
]
However, I cannot understand where this code should go. Tried putting requests as well as format separately inside data and batchUpdate but it did not work.

How about this sample script? If you want to update cell values and cell format, simultaneously, you can use spreadsheets.batchUpdate. The detail information is here.
The following sample imports [["value1"],["value2"]] to 'M2:M3' as shown in your script. As a sample, Sheet id is 0. The range is required to be inputted the GridRange.
Sample script :
var sheets = google.sheets('v4');
var request = {
spreadsheetId: SPREADSHEET_ID,
resource: {
"requests": [
{
"updateCells": {
"rows": [
{
"values": [
{
"userEnteredValue": {
"stringValue": "value1"
},
"userEnteredFormat": {
"textFormat": {
"bold": true
}
}
}
]
},
{
"values": [
{
"userEnteredValue": {
"stringValue": "value2"
},
"userEnteredFormat": {
"textFormat": {
"bold": true
}
}
}
]
}
],
"range": {
"sheetId": 0, // Sheet id
"startColumnIndex": 12,
"endColumnIndex": 13,
"startRowIndex": 1,
"endRowIndex": 3
},
"fields": "*"
}
}
]
},
auth: auth,
};
sheets.spreadsheets.batchUpdate(request, function(err, response) {
if (err) {
console.error(err);
return;
}
console.log(JSON.stringify(response, null, 2));
});
If I misunderstand your question, I'm sorry.
