Using Start Time and End Time instead of Hours
Most file formats require a column for Hours in order to upload data, but it is also possible to provide a Start Time and End Time column and have UpSheets calculate the hours automatically.
To do so, select the Enable Start/End Times option on the Import screen when importing your file:
![start_end](https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/j0x2GOjMS3/resources/3hKtDQmL6g/start_end.png)
On the following screen make sure you select columns for Start Time and End Time. You may optionally also select a column for Hours* which will be used if the Start Time and End Time are not set.
![times](https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/j0x2GOjMS3/resources/AdXfkcueFe/times.png)
If all fields are provided, the Start Time and End Time will be used instead of Hours
