Access files from local machine via analytical app in Alteryx Gallery

Hi,

I have an analytical app, which allows you to choose file on your local machine, process some data transformations and output the csv file on location specified by you (ex: also local machine). It works in Designer, but I would also like to run the analytical app in Gallery.

I have used Text Box to update the path, where the file should be outputted (similar as in this post: https://community.alteryx.com/t5/Alteryx-Server-Knowledge-Base/Folder-Browse-Not-Available-on-Gallery-Workaround/ta-p/48913), as File Browse doesn't work in Gallery. I receive an error: "Cannot access the folder". Is there any other workaround except from saving files on a network location that the server login has permission to access?

Thank you in advance!

Hi @OksanaBezpyata

Disconnect the Action tool from the output tool. You want the output written to the %temp% directory. That file should then be presented to the user at the end of the workflow. It should look something like this

Click on the file icon and the file should open on the user's computer in excel

Hi @OksanaBezpyata ,

If you want to upload a single file (in case of excel, only one sheet), it is totally possible to do it with the file browse tool.

Best,

Hi @OksanaBezpyata, I don't think there is a known workaround to have the Alteryx Server to write back your local machine.

Hi @OksanaBezpyata

It's difficult to diagnose this without seeing your workflow, but it sounds like the workflow is configured to write the output file to the path that the user enters into the text box, i.e. c:\work\somefolder\output.xlsx. When this runs on your computer it writes to "c:\work..." on your computer. When it runs on the gallery, it also tries to write to "c:\work\somefolder\output.xlsx" on the server. Since it's a server, the process that runs the workflow probably doesn't have the permissions required to access this path. If you run this manually, then your credentials probably don't have permissions, either. Even if the file did manage to get written, you'd either need access to the server or a share set up on the server to retrieve the file.

I think you have a few options available to you.

1. Configure your app so that it "opens the files from these tools" and select the output tool. This will open the file in a excel on the users computer, after which the user can save it anywhere they like. You may to change your output format to .xslx to get this to work properly

2. Send your output to a shared drive, where the gallery service account has access.

3. Have the user enter an email address in to the textbox and send the output to them.

Thank you very much for an answer!

Unfortunately, there is no possibility me to accomplish option 2, 3. But could you be more specific about option 1, where and how can I configure the app?

Thank you for your help!

On the Interface Designer, click the gear icon on the left.

Configure the output tool to write to %temp%filename.xlsx.

Hi @danilang

Thank you a lot! I have tried this option and it finishes working with success when I run it in Gallery. I specified %temp% in output file, but I can't find a file generated. I have attached the screen to show the way File_Name is created: it is created from three inputs specified by user.
