I am hitting a wall when trying to append data into spreadsheet what is the best to handle this, I know spreadsheet is Write to file and that is why it is not appending.
I know google sheet has the option but there should be an other way to handle this so I can share it with others.
Sorry for the late reply when I am getting the data it reads it and creates the file and then doesn’t save the loop data but overwrites the file instead of adding it to the next line.
You need to read the file first, merge input data with the data from file into n8n data structure, append new data, and write the entire file.
Without seeing your current workflow it is hard to tell if you really need the Loop node to append the data. Alternative could be a Code node or Set node that would do this for all new data at once. Depends on structure of the input.
Try posting your workflow. See the tip at the top of the message editing box on how to accomplish this. Real workflow is worth 1000 words.
