ITIDA Create Canonical JSON

See more Egypt ITIDA Examples

Demonstrates creating the canonical (ITIDA) version of a JSON document. The document in the example is the one at https://sdk.invoicing.eta.gov.eg/files/one-doc.json

Note: This example requires Chilkat v9.5.0.92 or greater.

  // See Global Unlock Sample for sample code.

  // Note: This example requires Chilkat v9.5.0.92 or greater.
  // (In v9.5.0.92, the "itida" encoding was added to StringBuilder's Encode method.)

  // Convert the contents of sb to the ITIDA canonical form.
  // Always pass utf-8 for the 2nd arg.
