    Thank you for sharing the sample file Jon.

    I was able to reproduce this issue and identify the cause. Specifically, the first column's title is an empty string. That is what is trying to be displayed between the square brackets, not the literal "[" nor "]" characters.

    To resolve this, simply edit the title of the first column to "ColumnA" for example. This resolves the warning and allows the File Upload to succeed.

    There is not a hard limit on file size that may be uploaded to the trial. Larger files are more sensitive to network outages though.

    At what stage does the File Upload wizard fail? Is it when the file is being transferred or is it at a later step?

    Hi, not sure to reply to Joel's question...does not seem to be a mechanism for replying so I will type an answer...I'm wondering if the trial version has been completely vetted on Windows 10 because I'm running into several complications with the tutorials as well which is making my experience frustrating.

    Nevertheless, I really like the interface and the potential of this app.

    I decided to use a smaller subset of my dataset - around 50 columns instead of the full 1400 something. Again, around 140K something rows. I did get a little further with this trimmed down set but one of the columns had "[]" which the wizard flagged. I can unselect this column from the load but it does not seem to refresh and continues to flag the column even though I unchecked it thus removing it from the load; the wizard does not seem to notice this. I noticed this same lack of refresh behavior when creating an infographic. I ended up creating a new infographic to get around that and tried the same approach with the file load wizard. I tried it three times but to no avail. Every time it flags the bad column and every time I uncheck it and the wizard does not seem to recognizer it.

    I can obviously remove the column from my spreadsheer and try again but at this point I'm discouraged with the trial version.

    Jon, yes the "Add answer" button is the correct way to respond.

    What is the data type (i.e. STRING, INT, LIST) of the column that is continuing to display "[]"? Is this for a data row or is this for the title of the column?

    Data type is string and the "[]" is for every row - it is the value not the title.

    Are you able to share some sample rows from the data set so that I could attempt to reproduce your observations?
    If you were able to successfully complete the file upload with the 50 columns you referenced, you can share the URL to this data in the Online Demo.

    Hi Joel, how do I share files? I don't see any way to attach screen prints or files.

    Okay. So I removed the column that had the "[]" and the error message still appears:

    At least one column name has invalid characters .description: []

    I did a search in Excel for this character and the search came up with nothing. I'm not sure what the ".description" is eluding to. I'm stumped.
