Comment puis-je obtenir regex soutien dans excel via une fonction, ou d'une fonction personnalisée?

Voici un post concernant l'utilisation de Regex dans Excel:

Espère que cela aide.

Et un autre qui utilise Python et IronSpread

J'ai essayé plusieurs solutions et compte tenu de mon manque d'expertise sur le VBA, j'ai trouvé la plupart d'entre eux trop lourde pour moi.
Le plus facile que j'ai trouvé était SeoTools pour Excel (http://nielsbosma.se/projects/seotools/).
A travaillé comme un charme pour moi.

Récemment, j'ai eu exactement la même question et après avoir lutté avec la création de mes propres outils et à les faire fonctionner correctement, j'ai trouvé un grand en ligne ADDIN qui est très FACILE à UTILISER.

C'est le créateur de l'extrait

Pour mon stage au cours des derniers mois, j'ai travaillé dans
le Marketing département de la Science et de la partie de mon travail a été de faire la
des données dans MS Access et de génération de rapports. Il s'agit d'obtenir
des listes de prospects à partir de diverses sources de données. Il était généralement un
assez simple exploit, impliquant une base de requêtes SQL. Cependant,
parfois, j'ai été remis données telles que les adresses qui ne correspondent pas à
le format standard utilisé par ELLE. Dans le pire des cas, les données ont été fournies dans
un pdf, ce qui signifiait que je ne pouvais seulement exporter vers un non-fichier texte délimité.
J'ai trouvé que j'avais vraiment besoin d'un couple générique de l'expression régulière
fonctions pour analyser les champs à importer dans MS Access. J'ai trouvé quelques
.xla exemples en ligne, mais je voulais vraiment un plus facile à utiliser, plus
étendu, et la bibliothèque portable. Je voulais aussi inclure quelques-uns de base
les modèles de sorte qu'il n'était pas nécessaire de ré-inventer la roue à chaque fois.

Donc, j'ai créé un simple Excel Add-In d'Expressions Régulières.xla qui ajoute
plusieurs fonctions personnalisées pour mettre en œuvre la norme VBScript regular
les expressions.

Ici est la site web

Je l'ai utilisé avec succès à l'extrait de texte utile à l'aide de regex.

Voici le code à l'addin
