Google Sheet API => Sheet creation OK but can't set specific defaultFormat - google-sheets-api

Question

I succeeded to create a sheet, but horizontal and vertical alignments are set to defaults, not the ones I tried to set.
Here is the code
spreadsheet_body = {
'properties': {
'title': str("sme_"+jour_heure.read()),
'defaultFormat': {
'horizontalAlignment': 'LEFT',
'verticalAlignment': 'MIDDLE'
}
}
}
print(spreadsheet_body)
# Création du fichier Google Sheet
request = service_sheet.spreadsheets().create(body=spreadsheet_body)
response = request.execute()
print (response)
My sheet is correctly created by vertical and horizontal alignments are not set.
print (spreadsheet_body)
prints:
{'properties': {'title': 'sme_18_04_2020\n', 'defaultFormat': {'horizontalAlignment': 'LEFT', 'verticalAlignment': 'MIDDLE'}}}
but
print (response)
prints:
{'spreadsheetId': '1F2o5F8B-efoAOkg-d3z_2tGcPhvlp8gtcvGOGkGvAGI', 'properties': {'title': 'sme_18_04_2020\n', 'locale': 'en_US', 'autoRecalc': 'ON_CHANGE', 'timeZone': 'Etc/GMT', 'defaultFormat': {'backgroundColor': {'red': 1, 'green': 1, 'blue': 1}, 'padding': {'top': 2, 'right': 3, 'bottom': 2, 'left': 3}, 'verticalAlignment': 'BOTTOM', 'wrapStrategy': 'OVERFLOW_CELL', 'textFormat': {'foregroundColor': {}, 'fontFamily': 'arial,sans,sans-serif', 'fontSize': 10, 'bold': False, 'italic': False, 'strikethrough': Fal ./..
Title is OK but verticalAlignment is not ...
What did I do wrong ?

Answer 1

i believe you want to create new sheet with required alignment, with your code everything is a string like "horizontalAlignment": "LEFT" anything between "" is string and line ends with ; instead of ,
try this for creating new sheet and alignment
function alignment(){
//change sheet name as per your requirement
var ss = SpreadsheetApp.getActiveSpreadsheet().insertSheet("yousheet");
var range = ss.getRange("A1:Z");
range.setHorizontalAlignment('left').setVerticalAlignment('middle');
}
