⊞ JSON Grid X

JSON Grid X

An online JSON viewer, formatter and diff tool — but built as a multi-cell workspace, not a single textarea.

  • Multi-cell grid: many JSON documents side by side, with tabs
  • Spreadsheet-style table view of arrays & nested objects
  • Pretty-print, beautify & validate JSON
  • Diff any two values across cells, color-coded
  • Converts Salesforce Apex debug output to JSON

🗺 Apex Flow X

Apex Flow X

Turn a Salesforce Apex, LWC or Java project into interactive class diagrams and call-flow charts — straight from a local folder.

  • Class diagrams for Apex, LWC and Java
  • Recursive method call-flow charts
  • Architecture map of a whole project folder
  • Cross-language links (LWC → Apex imports)
  • Pan & zoom; export the Mermaid definition

🐞 SF Debug Viewer X

SF Debug Viewer X

Paste a raw Salesforce Apex debug log and explore it as a navigable call tree instead of thousands of raw lines.

  • Collapsible Apex call tree
  • SOQL & DML breakdown with counts
  • Exceptions, stack traces & method timings
  • Multi-log tabs with global search
  • Custom highlighting & type filters

Why XTools?

Built especially for Salesforce developers, plus a general-purpose JSON workspace — with privacy and speed as first principles.

🔒

Private by design

Everything runs client-side. Your JSON, code, and debug logs are never uploaded to any server.

⚡

No install, no signup

Just open a URL. The tools also work offline once loaded — no account required.

🆓

Free & open source

All three tools are free and the source is on GitHub. If they save you time, you can buy me a coffee.
