Getting StartedKnown Limitations
Understanding the architectural boundaries of GiantJSON Viewer+ and when they might affect you.
TopicsHow to Analyze Large HAR Files on Android
Open, read, and analyze large HAR files directly on your phone without uploading. Full network traffic analysis with filtering, timing breakdowns, and privacy.
TopicsHow to Test REST & GraphQL APIs on Android
Send REST and GraphQL requests from your phone. Import Postman collections, use OAuth2, AWS Signature V4, and inspect responses of any size.
TopicsHow to Generate Sample JSON Test Data on Android
Generate JSON test data from 12 built-in templates or your own JSON Schema. Streaming engine, up to 100 GB, offline and free.
TopicsHow to Compare Two JSON Files on Android
Structural JSON and NDJSON diff on your phone: ignores formatting and key order, detects moved records, handles multi-gigabyte files. Pair list items by key, scope the compare, ignore noisy fields. Plus honest desktop alternatives.
TopicsHow to Diff Large JSON Files on Linux — Even Bigger Than RAM
gjxdiff, a Linux CLI for structural diff of huge JSON and NDJSON files: measured against jd, json-diff, jsondiffpatch, and jq on the same machine, with copy-paste commands, CI exit codes, and RFC 6902 patch export.
TopicsHow to Compare NDJSON Files When the Record Order Changed
Database exports and event logs reorder between dumps. The honest jq sort recipe, where it stops being enough, and key-based record pairing that absorbs reorders — measured up to 3.1 million records per side.
TopicsJSON Diff Out of Memory? Why It Happens and What Works
What "JavaScript heap out of memory" and ERR_STRING_TOO_LONG really mean, the measured failure points of common tools, and an escalation ladder from raising Node's heap to a disk-backed structural diff.
TopicsGenerate an RFC 6902 JSON Patch from Large Files
JSON Patch for API bodies, config sync, and audit trails: small-scale generators, their in-memory limits, and gjxdiff --patch, which writes a correct patch or refuses loudly — never a silent partial one.
