Konvertera Excel till CSV, TSV och Txt med JavaScript via C++

Spara arbetsbok till text eller CSV-format

Ibland vill du konvertera eller spara ett arbetsbok med flera flikar till textformat. För textformat (t.ex. TXT, TabDelim, CSV, etc.), sparar både Microsoft Excel och Aspose.Cells som standard endast innehållet i det aktiva kalkylbladet.

Följande kodexempel förklarar hur man sparar en hel arbetsbok till textformat. Ladda den källa arbetsboken, som kan vara vilken Microsoft Excel- eller OpenOffice-kalkylbladsfil som helst (såsom XLS, XLSX, XLSM, XLSB, ODS osv.) med valfritt antal kalkylblad.

När koden körs konverterar den datan i alla arbetsblad i arbetsboken till TXT-format.

Du kan ändra samma exempel för att spara din fil till CSV. Som standard är TxtSaveOptions.separator ett kommatecken, så ange inte en avskiljare om du sparar till CSV-format.

Spara textfiler med anpassad separator

Textfiler innehåller kalkyleringsdata utan formatering. Filen är en typ av ren textfil som kan ha anpassade avgränsare mellan sina data.
