Importare i dati CSV in un foglio di lavoro

Livello di programmazione: intermedio
Durata: 15 minuti
Tipo di progetto: automazione con un attivatore a tempo

Obiettivi

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

Informazioni su questa soluzione

Importa automaticamente i dati da file CSV in un unico foglio di lavoro di Fogli Google. Se lavori con più file CSV strutturati in modo simile, puoi utilizzare questa soluzione per centralizzare i dati in Fogli.

Come funziona

Lo script viene eseguito ogni giorno su un trigger basato sul tempo. Viene eseguita l'iterazione dei file CSV in una cartella designata e i dati di ogni file vengono aggiunti a un foglio di lavoro. Per impostazione predefinita, lo script rimuove la riga di intestazione di ogni set di dati CSV prima di aggiungere i dati all'ultima riga del foglio. Lo script invia un'email di riepilogo in cui sono elencati i file importati e li sposta in una cartella diversa per evitare l'elaborazione duplicata.

Lo script include anche funzioni che impostano file CSV di esempio per dimostrare questa soluzione.

Servizi Apps Script

Questa soluzione utilizza i seguenti servizi:

• Script service: crea il trigger basato sul tempo.
• Servizio Drive: recupera le cartelle utilizzate dallo script per archiviare i file CSV elaborati e non elaborati e li crea se non esistono. Recupera l'URL del progetto Apps Script da includere nell'email di riepilogo.
• Servizio fogli di lavoro: ottiene il foglio di lavoro in cui lo script aggiunge i dati da ogni file CSV.
• Servizio di base: utilizza la classe Session per ottenere l'indirizzo email dell'utente e il fuso orario dello script.
  • L'utente dipende da chi esegue lo script. Poiché lo script viene eseguito su un trigger basato sul tempo, l'utente è definito come la persona che ha creato l'attivatore.
  • Lo script utilizza il fuso orario per aggiungere la data e l'ora in cui è stato eseguito all'email di riepilogo.
• Servizio di utilità: analizza ogni file CSV in un array. Formatta la data aggiunta dallo script all'email di riepilogo.
• Servizio di posta: invia l'email di riepilogo dopo che i dati dei file CSV sono stati importati nel foglio di lavoro.

Prerequisiti

Per utilizzare questo esempio, devi disporre dei seguenti prerequisiti:

• Un Account Google (gli account Google Workspace potrebbero richiedere l'approvazione dell'amministratore).
• Un browser web con accesso a internet.

Configura lo script

1. Fai clic sul pulsante seguente per aprire il progetto Apps Script Importa dati CSV.
   Apri il progetto
2. Fai clic su Panoramica .
3. Nella pagina Panoramica, fai clic su Crea una copia .

Esegui lo script

1. Nel progetto Apps Script copiato, vai al file SetupSample.gs.
2. Nel menu a discesa della funzione, seleziona setupSample, quindi fai clic su Esegui. Questa funzione crea l'attivatore basato sul tempo, i file CSV, il foglio di lavoro e la cartella che lo script utilizza per essere eseguito correttamente.

3. Quando richiesto, autorizza lo script. Se nella schermata per il consenso OAuth viene visualizzato l'avviso Questa app non è verificata, continua selezionando Avanzate > Vai a {Nome progetto} (non sicuro).

4. Per visualizzare l'attivatore basato sul tempo al termine della configurazione, fai clic su Trigger .

5. Per visualizzare i file creati, apri la cartella [Esempio di Apps Script] Importa CSV su Google Drive.

6. Torna al progetto Apps Script e, nell'editor, vai al file Code.gs.

7. Nel menu a discesa della funzione, seleziona updateApplicationSheet e fai clic su Esegui.

8. Per visualizzare l'email di riepilogo con un link al foglio di lavoro con i dati importati, controlla nella posta in arrivo.

(Facoltativo) Reimposta la soluzione

Puoi reimpostare la soluzione per aggiornarla con i tuoi dati o riprovare la demo.

1. Nel progetto Apps Script, vai al file SetupSample.gs.
2. Nel menu a discesa della funzione, seleziona removeSample e fai clic su Esegui. Questa funzione elimina il trigger, i file e la cartella creati nella sezione precedente.
