      • JSON Tools

      Seven complementary tools that take you from read → edit → add → cross-dataset sync. All share the same JSONPath syntax so they chain naturally.

      Pick the Right Tool

      I want to…Use
      Extract specific fields from JSONJSON Value Extractor
      Batch add prefix/suffix, replace, overwriteJSON Node Edit
      Insert new fields after a specific nodeJSON Node Inserter
      Sort JSON arrays (with optional grouping)JSON Sort & Classify
      Swap values of two keysJSON Value Swapper
      Copy fields across JSON / key remapJSON Value Transformer
      Sync two JSON datasets by IDJSON Match & Update
      Translate i18n JSON into multiple languagesJSON Translate (in Translation Tools)

      Shared Capabilities

      • Browser-local processing: JSON parsing, JSONPath queries, and all edit operations run in your browser — source never uploads to a server
      • Unified JSONPath syntax: $..title, $.products[*].name, nested paths like zh.name — same expressions across all seven tools
      • Large-file mode: oversized JSON hides the textarea and routes through pure file I/O so tens of MB stay smooth
      • Chainable: pull fields with Extractor, batch-edit with Node Edit, regroup with Sort & Classify — a full pipeline without writing a script

      Common Combinations

      • i18n dictionary cleanup: Value Extractor pulls every title → translate/review → Node Edit overwrites them back
      • Product catalog regroup: Sort & Classify by category + price descending → Node Edit adds a promo prefix
      • Dataset sync: Export JSON A from the main DB and JSON B from CRM → Match & Update merges B's fresh fields into A by ID
