Question

How to get the last row with value in the new Google Sheets API v4 ?

i use this to get a range from a sheet:

mService.spreadsheets().values().get(\"I         


        

Answer 1

Answer 2

You can set the range to "A2:D" and this would fetch as far as the last data row in your sheet.

Answer 3

I managed to get it by counting the total rows from current Sheets. Then append the data to the next row.

rowcount = this.mService.spreadsheets().values().get(spreadsheetId, range).execute().getValues().size()

Answer 4

You don't need to. Set a huge range (for example A2:D5000) to guarantee that all your rows will be located in it. I don't know if it has some further impact, may be increased memory consumption or something, but for now it's OK.

private List<String> getDataFromApi() throws IOException {
        String spreadsheetId = "1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms"; 
        String range = "A2:D5000";
        List<String> results = new ArrayList<String>();
        ValueRange response = this.mService.spreadsheets().values()
                .get(spreadsheetId, range)
                .execute();
        List<List<Object>> values = response.getValues();
        if (values != null) {
            results.add("Name, Major");
            for (List row : values) {
                results.add(row.get(0) + ", " + row.get(3));
            }
        }
        return results;
    }

Look at the loop for (List row : values). If you have two rows in your table you will get two elements in values list.
