ImageRenderOptions

JsonSaveOptions nav konfigurējamu īpašību. Pārsūtiet instance uz JsonHandler.save_json() lai izmantotu noklusējuma serializācijas uzvedību.

JsonHandler

JsonHandler satur tikai statiskās metodes un nekad netiek instancēts.

JsonHandler.save_json 

JsonHandler.save_json(workbook, file_path: str, options: JsonSaveOptions | None = None) -> None

Eksportē pirmo darblapu uz JSON failu vietā file_path. Ja options ir None, noklusējuma JsonSaveOptions tiek izmantoti.

JsonHandler.save_json_to_dict 

JsonHandler.save_json_to_dict(workbook, options: JsonSaveOptions | None = None) -> dict

Serializē darblapu uz Python dict (vai list) un atgriež to, nerakstot nevienu failu. Noderīgi programmatiski apstrādes posmiem.

Moduļa funkcija

save_workbook_as_json

ImageRenderOptions

Sekojošais piemērs ieraksta pārdošanas tabulu un eksportē to uz JSON failu ar ISO datuma formatējumu.

from aspose.cells_foss import Workbook, JsonHandler, JsonSaveOptions
import datetime

wb = Workbook()
ws = wb.worksheets[0]
ws.name = "Sales"

# Header row
ws.cells["A1"].put_value("Date")
ws.cells["B1"].put_value("Product")
ws.cells["C1"].put_value("Amount")

# Data rows
ws.cells["A2"].put_value(datetime.date(2025, 1, 15))
ws.cells["B2"].put_value("Widget A")
ws.cells["C2"].put_value(1250.00)

ws.cells["A3"].put_value(datetime.date(2025, 1, 22))
ws.cells["B3"].put_value("Widget B")
ws.cells["C3"].put_value(840.50)

opts = JsonSaveOptions()

# Save to file
JsonHandler.save_json(wb, "sales.json", options=opts)

# Or retrieve as a Python dict
data = JsonHandler.save_json_to_dict(wb, options=opts)
print(data)

Piemēra izvade (sales.json):

{
  "Sales": [
    {"Date": "2025-01-15", "Product": "Widget A", "Amount": 1250.0},
    {"Date": "2025-01-22", "Product": "Widget B", "Amount": 840.5}
  ]
}
