Source Map Decoder
Map bundled positions (file:line:col) back to original source files using a .map file.
Source map (.map JSON)
| Bundled position | Original source | Line:Col | Symbol |
|---|---|---|---|
| bundle.js:12:345 | Not found in this map. | ||
| bundle.js:1:10500 | src/app.ts | 1:22 | — |
| chunk-XYZ.js:42:6 | Not found in this map. | ||
Inputs
- The
.mapfile (paste it or load it) - One or more bundled-file positions like
bundle.js:12:345
Output
The original source path, line, column, and (when present) the symbol name — the form you actually want to read.
Privacy
All decoding runs in your browser. The map and positions never leave the page.
