Diff línea a línea con añadidos, borrados y cambios
Original
Modified
Diff two pieces of text without firing up an IDE
Sometimes the thing you need to compare isn't JSON or code — it's a log snippet, a config file, an essay, or two versions of an email. A line-by-line diff shows you additions, removals, and modifications side by side, with options to ignore whitespace and case so you only see meaningful differences.
Use the comparer when you need to
Compare two log snippets
Paste before-and-after logs to find the line that changed when a deploy went sideways.
Diff prose or release notes
See exactly what changed between two drafts without running git diff or opening an editor.
Verify a copy-paste change
Confirm that the modified version differs only in the way you intended, not in extra invisible whitespace.
How to diff text quickly
- 1
Paste or upload the original text on the left.
- 2
Paste or upload the modified text on the right.
- 3
Toggle ignore whitespace or ignore case if needed, then click Compare.
Keep going
Diff JSON instead
Pick the JSON-aware comparer when both inputs are structured documents.
Format JSON before diffing
Pretty-print both sides first so the diff isn't dominated by indentation noise.
Minify before diffing
Strip whitespace from both inputs to focus the diff on real changes.
Decode encoded inputs
Decode Base64 first when the diff target is encoded text.
Common text-diff workflows
Paste both into the editor to find the entry that's missing or different between environments.
Confirm the new config differs from the old only in the lines you intended to change.

JSON Compare parsea JSON y compara la estructura. Esta herramienta trata la entrada como líneas de texto plano: ideal para logs, configs, documentación o cualquier contenido que no sea JSON.
Cuando se elimina una línea y se añade otra en la misma posición lógica, se agrupan como una modificación (ámbar) para que puedas ver el reemplazo de un vistazo.
Cambian cómo se comparan las líneas: el modo de whitespace colapsa secuencias de espacios y recorta los extremos antes de comparar; ignore case convierte a minúsculas solo para la comparación, pero el texto original se sigue mostrando en la salida.
Sí. Usa el botón Upload encima de cada editor para cargar un archivo de texto en Original o Modified, y luego pulsa Compare.
