Hello everyone, I keep on getting a "File structure cannot be determined" error message whenever I try to manually upload a JSON .txt and/or .csv wayy under 100MB (as pictured). Links to dataset: [KDD Cup 1999 Data](http://kdd.ics.uci.edu/databases/kddcup99/kddcup99.html) [NSL-KDD | Datasets | Research | Canadian Institute for Cybersecurity | UNB](https://www.unb.ca/cic/datasets/nsl.html) Looking for guidance as to how to resolve this issue. The file(s) is a DDOS dataset that I am looking into as a data analysis exercise. The goal is to build dashboards ![image](https://us1.discourse-cdn.com/elastic/original/3X/3/9/39088b986eea07b405fb48f7f5cf8a0cafd09a1b.png) ---

Hi, I've tried locally with the dataset provided, trying to upload each of the `.txt` file available and everyone worked without issues. It definitely doesn't work with other, non-textual, files. Could you please tell us the Kibana version you are using and the server OS where is running? thanks ---

Hey Marco, i'm using Ubuntu 20.04 inside a Windows 10 Home - VMware environment. Kibana version is v 7.12.1. That's strange, none of the formats works for me, gives me an error message everytime. What do you think it is? Thanks. ---

can you double check the csv format? when opening the .txt file do you see just rows of values separated by a comma? ---

Could you please check if this issue is somehow related: [Error importing a simple csv file on Data Visualizer · Issue #96425 · elastic/kibana · GitHub](https://github.com/elastic/kibana/issues/96425) ---
