Json Visualizer

A command-line devtools toolkit for working with JSON data. Check, validate, generate, format, lint, explain, convert, diff, preview, fix, and report on JSON structures — all from your terminal with persistent logging and history tracking.

Why Json Visualizer?

  • Works entirely offline — your data never leaves your machine
  • No external dependencies or accounts needed
  • Every action is timestamped and logged for full auditability
  • Export your history to JSON, CSV, or plain text anytime
  • Simple CLI interface with consistent command patterns

Commands

CommandDescription
json-visualizer check <input>Check JSON data for issues; view recent checks without args
json-visualizer validate <input>Validate JSON structure and syntax
json-visualizer generate <input>Generate JSON from a description or template
json-visualizer format <input>Format and prettify JSON data
json-visualizer lint <input>Lint JSON for style and structural issues
json-visualizer explain <input>Explain JSON structure in human-readable form
json-visualizer convert <input>Convert JSON to/from other formats
json-visualizer template <input>Create or apply JSON templates
json-visualizer diff <input>Diff two JSON structures to find changes
json-visualizer preview <input>Preview JSON rendering or output
json-visualizer fix <input>Auto-fix common JSON issues
json-visualizer report <input>Generate a report from JSON data
json-visualizer statsShow summary statistics across all actions
json-visualizer export <fmt>Export all logs (formats: json, csv, txt)
json-visualizer search <term>Search across all log entries
json-visualizer recentShow the 20 most recent activity entries
json-visualizer statusHealth check — version, disk usage, entry count
json-visualizer helpShow help with all available commands
json-visualizer versionPrint current version (v2.0.0)

Each data command (check, validate, generate, etc.) works in two modes:

  • With arguments — logs the input with a timestamp and saves to its dedicated log file
  • Without arguments — displays the 20 most recent entries from that command's log

Data Storage

All data is stored locally in ~/.local/share/json-visualizer/. The directory structure:

  • check.log, validate.log, generate.log, etc. — per-command log files
  • history.log — unified activity log across all commands
  • export.json, export.csv, export.txt — generated export files

Set the DATA_DIR environment variable in the script to change the storage location.

Requirements

  • Bash 4.0+ (uses set -euo pipefail)
  • Standard Unix tools: date, wc, du, tail, grep, sed, cat
  • No external packages or network access required

When to Use

  1. Validating API responses — pipe JSON output through json-visualizer validate to quickly verify structure before processing
  2. Formatting messy JSON — use json-visualizer format to prettify minified or poorly-indented JSON files for code review
  3. Comparing JSON configs — run json-visualizer diff to track changes between configuration versions across deployments
  4. Generating boilerplate — use json-visualizer generate and json-visualizer template to scaffold JSON structures for new projects
  5. Auditing JSON workflows — use json-visualizer stats, json-visualizer recent, and json-visualizer export to review your JSON processing history

Examples

bash
# Check a JSON string for issues
json-visualizer check '{"name": "test", "value": 42}'

# Validate a JSON file's structure
json-visualizer validate @config.json

# Format minified JSON for readability
json-visualizer format '{"a":1,"b":2,"c":[3,4,5]}'

# Lint JSON for style problems
json-visualizer lint '{"Name":"test"}'

# View statistics across all commands
json-visualizer stats

# Export all history as CSV
json-visualizer export csv

# Search for a specific term in all logs
json-visualizer search "config"

# View recent activity
json-visualizer recent

# Health check
json-visualizer status

Output

All commands output structured text to stdout. You can redirect output to a file:

bash
json-visualizer report mydata > report.txt
json-visualizer export json

Configuration

The data directory defaults to ~/.local/share/json-visualizer/. Modify the DATA_DIR variable at the top of script.sh to change the storage path.
