Fictional teaching inputs. Keep originals, reference answers and actual tool outputs separate.

In Excel document tools choose JSON to Excel and load orders.json. Expect orders and meta sheets, 2+1 data rows. All number lexemes remain text. Invalid JSON must fail; reload the correct original rather than deleting a record. For a separate calculation workbook, load quantity.csv in CSV to Excel, keep id Text and select Number only for quantity. Check two numeric values totaling 5 while exact IDs remain text. Do not treat null and empty note cells as reversible JSON.
