A user-friendly Python library for seamless bidirectional conversion between Excel spreadsheets and Pydantic models

SerializableExcel

A user-friendly Python library for seamless bidirectional conversion between Excel spreadsheets and Pydantic models using declarative syntax similar to SQLAlchemy.

Quick Start

from serializable_excel import ExcelModel, Column

class UserModel(ExcelModel):
    name: str = Column(header="Name")
    age: int = Column(header="Age")
    email: str = Column(header="Email")

# Read from Excel file
users = UserModel.from_excel("users.xlsx")

# Write to Excel file
UserModel.to_excel(users, "output.xlsx")

# Or work with bytes for API usage
excel_bytes = UserModel.to_excel(users, return_bytes=True)
users = UserModel.from_excel(file_bytes)
