Hello,  
in the data visualizer of the Machine learning, we used to have a feature to upload a csv.  
there is blog about that https://www.elastic.co/blog/importing-csv-and-log-data-into-elasticsearch-with-file-data-visualizer

It worked very fine in version 6 when the csv does not have a timestamp.  
I migrated from version 6.5 to version 7. and now it does not work anymore if the csv does not contain any timestamp.

The error message is:

_File could not be read_  
_[illegal\_argument\_exception] Could not find a timestamp in the sample provided_

How can I overcome this ?  
this feature was very useful indeed !

For a perfectly formed CSV file with the same number of columns in every row it should still work without a timestamp in version 7.

I put more advice about this in [https://github.com/elastic/kibana/issues/63526#issuecomment-738138801](https://github.com/elastic/kibana/issues/63526#issuecomment-738138801), but the TL;DR is that the experience for CSV files that don't have the same number of columns in every row or are corrupt in some other way is much better in 7.10.
