Merge JSON

Documentation

• Class name: SaltMergeJSON
• Category: SALT/JSON
• Output node: False

The SaltMergeJSON node is designed to merge two JSON strings into a single JSON string, effectively combining their contents. This node is particularly useful in scenarios where integrating data from multiple JSON sources is required.

Input types

Required

• json_input1
  • The first JSON string to be merged. It plays a crucial role in the merging process as it forms the base onto which the second JSON string's contents are added.
  • Comfy dtype: STRING
  • Python dtype: str
• json_input2
  • The second JSON string to be merged with the first. Its contents are added to those of the first JSON string, contributing to the creation of the merged JSON output.
  • Comfy dtype: STRING
  • Python dtype: str

Output types

• json_output
  • Comfy dtype: STRING
  • The resulting JSON string after merging the contents of the two input JSON strings. It represents the combined data structure.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
