Kako si zapomniti ali shraniti prejšnjo vrednost celice spremenjene celice v Excelu?

Običajno bo pri posodabljanju celice z novo vsebino prejšnja vrednost pokrita, razen če razveljavite operacijo v Excelu. Če pa želite obdržati prejšnjo vrednost za primerjavo s posodobljeno, bo shranitev prejšnje vrednosti celice v drugo celico ali v komentar celice dobra izbira. Metoda v tem članku vam bo pomagala doseči.

Shranite prejšnjo vrednost celice s kodo VBA v Excelu

Shranite prejšnjo vrednost celice s kodo VBA v Excelu

Recimo, da imate tabelo, kot je prikazano na spodnji sliki zaslona. Če se je katera koli celica v stolpcu C spremenila, želite shraniti njeno prejšnjo vrednost v ustrezno celico stolpca G ali samodejno shraniti v komentar. Za dosego tega naredite naslednje.

1. Na delovnem listu je vrednost, ki jo boste shranili pri posodabljanju, z desno miškino tipko kliknite jeziček lista in izberite Ogled kode v meniju z desnim klikom. Oglejte si posnetek zaslona:

2. Na odprtju Microsoft Visual Basic za aplikacije okno, kopirajte spodnjo kodo VBA v okno Code.

Naslednja koda VBA vam pomaga shraniti prejšnjo vrednost celice določenega stolpca v drug stolpec.

Opombe: V kodi številka 7 označuje stolpec G, v katerega boste shranili prejšnjo celico, in C: C je stolpec, v katerega boste shranili prejšnjo vrednost celice. Prosimo, spremenite jih glede na vaše potrebe.

3. klik Orodja > Reference da odprete Reference - VBAProject pogovorno okno, preverite Izvajanje Microsoftovih skriptov in na koncu kliknite OK . Oglejte si posnetek zaslona:

4. Pritisnite druga + Q tipke za zapiranje Microsoft Visual Basic za aplikacije okno.

Od zdaj naprej, ko se vrednost celice v stolpcu C posodobi, se prejšnja vrednost celice shrani v ustrezne celice v stolpcu G ali shrani v komentar, kot je prikazano spodaj.

Shrani prejšnje vrednosti celic v druge celice:
