Pulling a source's file name into table as a field

[RMDNA]

Hi all,

I have a report built from .csv files in Blob storage. All the .csv files are titled "model_output_[timestamp]).

What I'd like to do is pull that timestamp into the table as a field so I can concat it into a column of "Model_[timestamp]" and join it to an ever-growing master list of model results.

Another thing I've tried is referencing the table at the "import CSV" step to get a list of the files, then pulling the timestamp out of the tilename. At that point, though, there's nothing to tie it back to the correct table (example below).

@RMDNA,

You may use Text.BetweenDelimiters to add a custom column.

Text.BetweenDelimiters([Filename], "[", "]")

Hi @v-chuncz-msft,

I already have the timestamp column, but would need it to carry over to the table once it's expanded, however. That's what I'm looking for - a column in a table referencing its source file's name.

Maybe this will help. The "model iteration" column is what I'm trying to create. At the moment, I'm copy-pasting the correct timestamp. What I'd like to do is pull the timestamp from my previous picture into this table so I can create that column.
