# Codeunit 1237 "Get Json Structure"

> Codeunit 1237 "Get Json Structure" in Base Application (System.IO). 3 public procedures. Present since at least BC23, still in BC30.

Base Application · System.IO · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/System/DataExchange/GetJsonStructure.Codeunit.al) · facts from BC29

## Procedures

- `GenerateStructure(Path: Text; var XMLBuffer: Record "XML Buffer")`
- `JsonToXML(JsonInStream: InStream; var XMLOutStream: OutStream)`
- `JsonToXMLCreateDefaultRoot(JsonInStream: InStream; var XMLOutStream: OutStream)`

## Triggers

OnRun

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 1297 "Http Web Request Mgt."](../codeunit/1297.md) (6 calls: `GenerateStructure → AddHeader`, `GenerateStructure → GetResponse`, `GenerateStructure → Initialize`, …)
- [Codeunit 4100 "Temp Blob"](../codeunit/4100.md) (2 calls: `GenerateStructure → CreateInStream`, `GenerateStructure → CreateOutStream`)
- [Codeunit 1235 "XML Buffer Writer"](../codeunit/1235.md) (1 call: `GenerateStructure → GenerateStructure`)

## Called by

- [Codeunit 1281 "Update Currency Exchange Rates"](../codeunit/1281.md) (2 calls: `CreateDataExchange → JsonToXML`, `CreateDataExchange → JsonToXMLCreateDefaultRoot`)
- [Codeunit 1235 "XML Buffer Writer"](../codeunit/1235.md) (1 call: `GenerateStructureFromPath → GenerateStructure`)
- [Codeunit 1238 "Suggest Col. Definition - Json"](../codeunit/1238.md) (1 call: `GenerateDataExchColDef → GenerateStructure`)

## Recent changes

- 2026-10-02 [#10755 Migrate Http Web Request Mgt. callers to native HttpClient](../../changes/bcapps/10755.md) (main, BC30, refactor)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: none

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "Get Json Structure")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
