You can rename accounts from the Tiller Console under the Account Summary.
Log in to the Tiller Console
Scroll down to Account Summary.
Click the Edit drop down menu next to any account name.
Click Rename.
Rename the account and click the blue Rename button to save your changes.
ℹ️ The update will be reflected in your spreadsheet after your next account refresh and fill and only for new entries. The account names for existing transactions will not change.
Update account names for existing data
If you renamed an account after you'd already created a sheet and filled the accounts data the data in the sheet will not update with the new account name. You'll need to manually correct the data.
Open the Transactions sheet
Turn on the Filter in the Transactions sheet
Filter the Transactions sheet to only show transactions for an account that has an updated name you want to correct. Keep in mind that some accounts may have the same name (e.g. CREDIT CARD) so you may also need to filter on the Account # column.
Use the Fill Handle to quickly update existing account data with the new name.
Unhide the Balance History sheet (View Menu > Hidden sheets)
Repeat steps 2-4 for Balance History entries
Update Accounts sheet dropdown selections (if applicable)
ℹ️ The nicknames also do not show up in the daily email summary at this time. Vote for this feature request on the Tiller Community if you would like to see your account nicknames appear in the daily email summary.
