Descrizione

Utilizzare questa funzione per creare rapidamente e facilmente alias per le celle dei fogli di calcolo. Si legge le etichette di testo già create in una colonna e le riporta come alias nella colonna successiva. Ad esempio, le etichette di testo nella colonna A possono essere utilizzate per creare alias per le celle nella colonna B. Dalla versione 2022.03.21, se si include del testo tra parentesi, solo quel testo diventerà l'alias. Ad esempio, "Altezza dell'estremità superiore (topHeight)" come etichetta (senza virgolette) creerà l'alias topHeight nella colonna successiva.

Utilizzo

Evidenziare le celle contenenti le etichette di testo ed eseguire la macro. Le celle adiacenti nella colonna successiva ora conterranno gli alias creati con i valori di testo delle celle evidenziate.

Screenshot 1 di EasyAlias, le etichette di testo della colonna A vengono utilizzate per creare gli alias nella colonna 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
