spreadsheet-handling 0.1.0b3

Composable pipelines for spreadsheets (JSON/YAML/CSV/XLSX) with FK helpers, validation, and IO routing.

Spreadsheet Handling

Spreadsheet Handling is a Python toolkit for packing/unpacking and orchestrating tabular data.
It converts between JSON, CSV, and Excel (XLSX/ODS) while preserving relationships such as foreign keys, indexes, and hierarchies.
The goal is to make complex spreadsheet models easier to validate, transform, and round-trip into structured formats.
