Following this, I have found that the software that we use allows it to be imported via a different method.
Each row of data can be condensed into a single cell. The formula is then repeated down for all 365 rows. This can then be imported.
=CONCATENATE(A1,",",B1,",",C1,",",D1,",",E1,",",F1,",",G1,",",H1,",",I1,",",J1,",",K1,",",L1,",",M1,",",N1,",",O1,",",P1,",",Q1,",",R1,",",S1,",",T1,",",U1,",",V1,",",W1,",",X1,",",Y1,",",Z1,",",AA1,",",AB1,",",AC1,",",AD1,",",AE1,",",AF1,",",AG1,",",AH1,",",AI1,",",AJ1,",",AK1,",",AL1,",",AM1,",",AN1,",",AO1,",",AP1,",",AQ1,",",AR1,",",AS1,",",AT1,",",AU1,",",AV1)
This may not help everyone but it has worked for us.
Kind regards,
James
