MATLAB: Readcell does not import last columns when first columns are empty (2019a)

Question

readcell('test.xls') does not import last n columns, when first n columns are empty.

i.e. instead of

{missing} {missing} {a} {b} {c} {d}

I will get

{missing} {missing} {a} {b}

When I know the number of columns I have I can use i.e.:

readcell('test.xls', 'Range', 'A:F') – in this case I have the last columns, but the leading empty columns are removed:

{a} {b} {c} {d}

Is there a way to get all the columns (including empty one)?

Edit:

readcell('test.xls', 'Range', '') – helps when one do not know the number of columns, but do not include the missing leading rows.

Answer 1

If you know the number of columns, then you can use below commands to get all columns including the empty ones.

opts = spreadsheetImportOptions('NumVariables',6,'DataRange', 'A:F');
M = readcell('test.xlsx', opts);
