# Portable Text Conversion
Convert external content (HTML, Markdown) into Portable Text for Sanity. Three main approaches:
1. **`markdownToPortableText`** — Convert Markdown directly using `@portabletext/markdown` (recommended for Markdown)
2. **`htmlToBlocks`** — Parse HTML into PT blocks using `@portabletext/block-tools` (for HTML migration)
3. **Manual construction** — Build PT blocks directly from any source (APIs, databases, etc.)
## Portable Text Specification
Understand the target format before converting. PT is an array of blocks:
```json
[
{
"_type": "block",
"_key": "abc123",
"style": "normal",
"children": [
{"_type": "span", "_key": "def456", "text": "Hello ", "marks": []},
{"_type": "span", "_key": "ghi789", "text": "world", "marks": ["strong"]}
],
"markDefs": []
},
{
"_type": "block",
"_key": "jkl012",
"style": "h2",
"children": [
{"_type": "span", "_key": "mno345", "text": "A heading", "marks": []}
],
"markDefs": []
},
{
"_type": "image",
"_key": "pqr678",
"asset": {"_type": "reference", "_ref": "image-abc-200x200-png"}
}
]
```
**Key rules:**
- Every block and span needs `_key` (unique within the array)
- `_type: "block"` is for text blocks; custom types use their own `_type`
- `markDefs` holds annotation data; `marks` on spans reference `markDefs[*]._key` or are decorator strings
- Lists use `listItem` ("bullet" | "number") and `level` (1, 2, 3...) on regular blocks
