## Examples of NER/IOB data that can be converted with `spacy convert`
-spacy JSON training files were generated with:
+To convert an IOB file to `.spacy` ([`DocBin`](https://spacy.io/api/docbin))
+for spaCy v3:
+```bash
+python -m spacy convert -c iob -s -n 10 -b en_core_web_sm file.iob .
```
+
+See all the `spacy convert` options: https://spacy.io/api/cli#convert
+
+---
+
+The spaCy v2 JSON training files were generated using **spaCy v2** with:
+
+```bash
python -m spacy convert -c iob -s -n 10 -b en file.iob
```
+
+To convert an existing JSON training file to `.spacy` for spaCy v3, convert
+with **spaCy v3**:
+
+```bash
+python -m spacy convert file.json .
+```

### Converters {#converters}
-| ID | Description |
-| ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| `auto` | Automatically pick converter based on file extension and file content (default). |
-| `json` | JSON-formatted training data used in spaCy v2.x. |
-| `conll` | Universal Dependencies `.conllu` or `.conll` format. |
-| `ner` | NER with IOB/IOB2 tags, one token per line with columns separated by whitespace. The first column is the token and the final column is the IOB tag. Sentences are separated by blank lines and documents are separated by the line `-DOCSTART- -X- O O`. Supports CoNLL 2003 NER format. See [sample data](%%GITHUB_SPACY/extra/example_data/ner_example_data). |
-| `iob` | NER with IOB/IOB2 tags, one sentence per line with tokens separated by whitespace and annotation separated by `\|`, either `word\|B-ENT`or`word\|POS\|B-ENT`. See [sample data](%%GITHUB_SPACY/extra/example_data/ner_example_data). |
