Hi @Yan_Mednis
Since you have it on a TFJS format, I think you might be able to do the loop using Javascript.
Do you want to just upload this batch of images from the catalogue or is it a service you are building?
for the output, I’d focus on generating a CSV with the data and then import it on Sheets, might be easier than using the Sheets api (if you don’t know that yet)
@Jason might have some much better insights than mine on this.
