I have an issue with the configuration of the Excel Reader node and I’m not sure if it’s on me or the node. I want to describe the issue with an example:
I want to import an Excel sheet containing sample data. There is a column called “Sample Name”. The user enters usually a string type sample name like “my_sample_name”. Now I got an Excel sheet with numeric sample names like “1”, “2”, “3” etc. For me, these are still samples names and they should be extracted as strings (as specified in the Transformation tab of the Excel Reader configuration). But the nodes extracts them as integers, which leads to fails downstream.
I always have a lot of troubles with the data type transformation in the Excel Reader node. The output data types change every time there is a small difference, although I specifically set the data type to string and check the Enforce types box. The node seems to prioritize its automatic data type detection higher than the manual data type configuration by the user.
I would like to force the Excel Reader node to extract everything in string format and do the parsing on my own as a workaround. How can I do this?
Thanks in advance.
