It's the most wonderful time of the year - Santalytics 2020 is here! This year, Santa's workshop needs the help of the Alteryx Community to help get back on track, so head over to the Group Hub for all the info to get started!
Just jumping in with news of a new feature coming in the next release (after 10.0).
Going forward, if you specify an .xlsx file with no sheet name, we will automatically open the first sheet (or only sheet if the file only has one).
How do you know which sheet will be "first"? Very good question. My understanding right now is that it'll be the last sheet modified, but I'm not 100% sure about this. I know that in the internal XML, the list of sheets doesn't appear to be in any particular order. So, what we can say is that you'll get the first sheet as written by Excel in the internal XML file, but beyond that we cannot guarantee which sheet you'll get in a multi-sheet file.
If your files all have one sheet each, then this might work well for you.
The request we added this for was a person who said "I have an Excel file with only one sheet in it, so why do I have to specify a sheet name?"
We thought that was a good idea and went one further by supporting files with more than one sheet as well (although it's not guaranteed which sheet you'll get in that case). So, there's really no option here, just if you don't tell us which sheet to read, we'll read the first one. Also, this is only for read and does not work when writing or appending.
Your idea of reading "all" sheets is interesting. How would you expect that to work if the sheets have different numbers of columns and conflicting "field names" and/or datatypes?
I'd love to hear your thoughts if you'd like to elaborate.
Maybe it would be more straight forward not to change the Input Tool at all. Instead, the Directory Tool could be changed. You could add a checkbox which would give you the option to show you all the different sheets within an excel file each as its own line in the directory
You can therefore filter the sheets you want to include and exclude and then pass through through the dynamic input tool like normal
