Install

pip install notion-api-utils

Usage

from notion_api_utils import Schema, Field, Title, RichText, Number, Select, Date, to_notion_properties

# Define a schema mapping your data to Notion properties
schema = Schema(fields={
    "name":   Field("Name", Title),
    "email":  Field("Email", Email),
    "age":    Field("Age", Number),
    "status": Field("Status", Select),
    "date":   Field("Created At", Date),
})

# Your data
data = {
    "name": "Lucas",
    "email": "[e-mail]",
    "age": 25,
    "status": "Active",
    "date": "2026-03-25",
}

# Convert to Notion properties JSON
properties = to_notion_properties(data, schema)
# Use `properties` in your Notion API call body

Output:

{
  "Name": {"title": [{"text": {"content": "Lucas"}}]},
  "Email": {"email": "[e-mail]"},
  "Age": {"number": 25},
  "Status": {"select": {"name": "Active"}},
  "Created At": {"date": {"start": "2026-03-25"}}
}

})

data = {"nome_completo": "Lucas"}
properties = to_notion_properties(data, schema)
