Description

Utilisez cette fonction pour créer rapidement et facilement des alias pour les cellules de vos feuilles de calcul. Elle prend les étiquettes de texte que vous avez déjà créées dans une colonne et les utilise comme alias dans la colonne suivante. Par exemple, les étiquettes de texte de la colonne A peuvent être utilisées pour créer des alias pour les cellules de la colonne B. Depuis la version 2022.03.21, si vous incluez du texte entre parenthèses, seul ce texte sera l'alias. Par exemple, "Height of top end (topHeight)" comme étiquette (sans les guillemets) fera l'alias de topHeight dans la colonne suivante.

Utilisation

Mettez en surbrillance les cellules contenant les étiquettes de texte et exécutez la macro. Les cellules adjacentes de la colonne suivante contiennent désormais des alias créés à partir des valeurs de texte des cellules mises en surbrillance.

Capture d'écran EasyAlias1, les étiquettes de texte de la colonne A sont utilisées pour créer les alias de la colonne B.

EasyAlias.FCMacro.py

This macro can be used to easily create aliases based on the contents of selected spreadsheet
cells in the previous column. As an example, suppose you wish to have the following:

A1: content = 'radius', B1: content = '5', alias = 'radius'
A2: content = 'height', B1: content = '15', alias = 'height'

The traditional way to set this up would be:
Select A1
Enter radius
Select B1
Enter 5
Right-click B1
Select properties
Select Alias
Enter radius
click OK
Select A2
Enter height
Select B2
Enter 15
Right-click B2
Select Properties
Select Alias
Enter height
Click OK

Using this macro, the work flow becomes:
Select A1
Enter radius
Select B1
Enter 5
Select A2
Enter height
Select B2
Enter 15
Select A1 through A2
Run the EasyAlias macro
Done
