How to identify cell is merged cell with google sheets api - go

Question

I'm using Go API https://developers.google.com/sheets/api/quickstart/go
I have a sheet looks like this and want to automate some cell filling logic
| B | C |
--+------+------+
1 | b1 | c1 |
--+------+ |
2 | b2 | |
--+------+------+
3 | b3 | |
--+------+------+
While using readRange := "B1:C" by
resp, _ := s.srv.Spreadsheets.Values.Get(spreadsheetId, readRange).Do()
for _, row := range resp.Values {
...
}
I can't tell the difference between C2 and C3. In this case, I would like to fill some values to C3 but not C2. How do I check this via API?

Answer 1

You want to retrieve the information of merge cells in a sheet using Sheets API.
From your replying, I could understand like above. If my understanding is correct, the method of spreadsheets.values.get cannot retrieve the information of merge cells. In this case, please use the method of spreadsheets.get. The modified script is as follows.
Modified script:
ranges := []string{"B1:C"}
resp, _ := s.srv.Spreadsheets.Get(spreadsheetId).Ranges(ranges...).Do()
for _, sheet := range resp.Sheets {
for _, merge := range sheet.Merges {
fmt.Printf("%#v\n", merge)
}
}
Note:
This modified script supposes that you have already used Sheets API.
Range of B1:C means B1:C of the first tab.
When you run above script, you can retrieve the coordinates of the merged cells as the GridRange like below.
{
"sheetId": 0,
"startRowIndex": 0,
"endRowIndex": 2,
"startColumnIndex": 2,
"endColumnIndex": 3
}
This GridRange is C1:C2 of sheet ID 0 as the a1Notation.
From above result, it is found that C1:C2 is the merged cell.
In this case, when the value is put in C1, the value is displayed. But when the value is put in C2, the value is not displayed. Please be careful this.
If you want to put the value using the GridRange, you can use the method of spreadsheets.batchUpdate.
