I have a excel file which is semi-structured. There is data in a table, but there are dividers in certain rows that should needs to be ignored.
The processing of the data should start with the column headers(Col1 , col2 ....) and only process the rows with actual data.
Could anyone suggest the way to achieve this using copy activity in adf .
My source is xls file and target is ADLA (Parquet file)
Any help appreciated. Thanks in advance.
The most closest solution is that you need manually choose data range in the excel file:

I have some CSV files that I want to copy to a specific folder in ADLS based on the date column within the file.
i.e. CSV file has a column named "date" that reads "2022-02-23" on all rows. I want to copy that file to a folder that has the corresponding year and month, such as "/curated/UK/ProjectABC/2022/02"
I've got a Lookup activity that's pointing to the source CSV file and populating a Set Variable activity with the month using this dynamic content - #substring(string(activity('Lookup1').output.firstrow.date),5,2)
Would this be the right approach, to use a variable?
I cant use variables in the Directory portion of the Sink Dataset, as far as I know.
Have you come across this situation before?
Sounds like you're on the right path. You can use absolutely use Dataset parameters:
Then populate them in your pipeline using a variable (or parameter, or expression):
In pentaho data integration, how do I import a list of xlsx files that are in the same folder?

If your excel column name and sheet name are always same then you can use THIS solution. Here I have take all xlsx file from source folder and convert one-by-one file as csv.
But if your excel columnname and sheet name are dynamic or you need some dynamic solution. Then you can use my another stackoverflow solution from Here

Data Files is in csv format and the Header is at 4th row in the csv file.
i want to use the header as is what is available in the csv data file.

Add a Surrogate Key transformation and then a Filter transformation to filter out row number 4.
You need to first uncheck the "First row as header" in your CSV dataset. Then you can use the "Skip line count" field in the copy data activity source tab and skip any number of lines you want.

I'm guessing you didn't check Stop reading on encountering empty rows, and that it's reading empty rows from your excel file.
Please try with checkbox checked.
I want to make a csv file that I can upload in my Google Calendar.
The mandatory headers for a file to upload are
Subject, Start date, Start time
But in Talend you can't make a column name with a space between the words, anybody know how I can fix this?
Maybe you can generate the first line with a "tFixedFlowInput" and complete your CSV file without column titles by changing in your output component the parameter "Include Header".
Don't forget to check the parameter "append" when you insert your data after
