I am stuck with inserting data into my MS Access Database. I already converted the data into cell array but it still returns me the error indicating that I am inputting the wrong data type.

C =
'SGX 8873 K'
>> iscell(C)
ans =
1
>> datainsert(conn,'VehicleLocation','col2','C')
Error using database/datainsert (line 58)
Input data must be a cell array or numeric matrix.
Been stuck on inserting the data into the database for quite some time now. The input data 'C' is already verified as cell array by the command iscell(C). Anybody got any idea what am I doing wrongly? Thanks.

Umakant, examine the below:
>> 'ABC'
ans =
ABC
>> {'ABC'}
ans =
'ABC'
When you see a string with quotes around it and indented, that is indicating a cell array containing the string; if it were a plain string then it would be displayed without the quote marks or indentation.

Umakant, I am currently using r2015a.
I have attached a photo of the variable editor, which shows that C is a 1x1 cell.

Guessing you want to remove the quotes from around C in the datainsert statement. You are trying to insert the single character 'C', rather than your variable C.

Cell contents reference from a non-cell array object.
Error in database/datainsert (line 72)
insertField = [ insertField fieldNames{i}]; %#ok
Thanks for the prompt reply. However, MATLAB still indicates that I am not inputting a cell array data. Any idea how to solve this problem?

datainsert(conn,'VehicleLocation', {'col2'}, C)
The column names must be cell array of string.

datainsert(conn,'VehicleLocation',{'col2'},C)
Error using database/datainsert (line 106) [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1.
Tried doing it before but couldn't work.

Sorry, I do not have that toolbox, so I cannot check the code to see what is happening.

Are you sure you already created a database?

You do not have a column named 'col2', you have a column named 'LicensePlate'

Alright thanks! That solved my problem. But now I am currently stuck at inserting multiple columns of data in one instance. Any ideas?
