Pulisci i dati in un foglio di lavoro

Livello di programmazione: intermedio
Durata: 20 minuti
Tipo di progetto: componente aggiuntivo Editor

Obiettivi

  • Comprendi cosa fa la soluzione.
  • Scopri cosa fanno i servizi Apps Script all'interno soluzione.
  • Configura lo script.
  • Esegui lo script.

Informazioni su questa soluzione

Pulisci i dati del foglio di lavoro rimuovendo automaticamente righe e colonne vuote, ritagliare il foglio di lavoro fino ai bordi dell'intervallo di dati e riempire gli spazi vuoti i dati.

Demo della formattazione di un componente aggiuntivo in un foglio di lavoro

Come funziona

Lo script esegue le seguenti funzioni:

  • Elimina righe vuote: all'interno di un intervallo selezionato, lo script identifica di righe e le elimina. Se le celle all'interno di una riga contengono spazi, la riga non è considerato vuoto.
  • Elimina colonne vuote: all'interno di un intervallo selezionato, lo script identifica le colonne e le elimina. Se le celle di una colonna contengono spazi, la colonna non viene considerata vuota.
  • Ritaglia foglio per l'intervallo di dati: lo script identifica il punto in cui termina l'intervallo di dati. ed elimina le righe e le colonne in eccesso.
  • Compila righe vuote: lo script copia e incolla i contenuti della cella attiva selezionata nelle celle vuote nelle righe sottostanti. Lo script si interrompe Incollare contenuti quando rileva una riga che non è vuota o raggiunge la fine dell'intervallo di dati.
