Hi @JulieSarah ,

You need to convert your data into Prodigy's JSONL format. You're passing the incorrect format into Prodigy that's why you see an error. Since you already have a spaCy file, you can convert it using this script: [Script: Load data in spaCy v3's .spacy format](https://support.prodi.gy/t/script-load-data-in-spacy-v3s-spacy-format/4369)

So again, what you can do is:

IOB -\> .spaCy file (save it into a serialized file [using the DocBin construct](https://spacy.io/api/docbin#to_disk)) -\> Prodigy JSONL file (using the script provided, which you can edit based on your needs)
