Reading excel file by time

Dear team

I am trying to read an excel file line by line ever minute (Like every minute it return a line from the list), I tried the loopwhile and a python node with time.sleep(60) but It didn’t work.

I really need your help friends.

can you please post more of your workflow? I am not sure I understand what you are trying to do. also posting your work with any error messages and code would be helpful

It might be better if you just use the graph in automatic node. It will re-execute and that will force your graph to re-execute.


As in the screen, now I want to return a line every minute.

Can you please explain more.

I wouldn’t go automatic node but Periodic mode. Place a DateTime.Now node, build a DateTime to start with (say noon today), set the runmode to periodic with a execution time of 1000 ms. Subtract the two datetimes and you will get 1 minute intervals. Round that off to the nearest minute and use that to get an item at the desired index on each subsequent run.

thank you
I will try it

First I thought of periodic…

Bear in mind that Periodic mode will re-execute the entire graph - so if it’s heavy, it may be a slow approach while it calculates (Also - it will hit an infinite loop, i.e freeze, if the time to run the graph is longer than the period).

Well it just re-executes the bits downstream from the DateTime now, but the volume of re-execution, and the time to execute vs the run frequency is good to keep in mind.
