Locale support in AppSheet

The following sections summarize the locale support in AppSheet:

• Locale for Google Sheets
• Locale for AppSheet 
• Configure the locale
• About the compatibility locale
• Locale for Excel
• Locale for Smartsheet

Locale for Google Sheets

The Google Sheets Locale setting controls how Date, DateTime, Decimal, Percent, Price (Currency), and Time values are entered into Google Sheets. See Set a spreadsheet's location and calculation settings.

For Date value, when the Google Sheets Locale is United States, dates are normally entered in MM/DD/YYYY format. Conversely, when the Google Sheets Locale is United Kingdom, dates are normally entered in DD/MM/YYYY format.

For Decimal values, when the Google Sheets Locale is Japan, United Kingdom, or United States, you must enter a period as the decimal separator between the whole and fractional parts of Decimal, Percent, and Price values. Conversely, when the Google Sheets Locale is Brazil, France, or Germany, you must enter a comma as the decimal separator.

If your Google Sheet was generated as a response sheet for a Google Form, setting the sheet locale may not automatically apply the new locale formatting to existing columns. To fix this, highlight the column and apply the appropriate formatting from the Format > Number menu in the toolbar.

Locale for AppSheet

When configuring table settings, the AppSheet Data locale setting in the Localization section controls how AppSheet reads and writes values from Google Sheets. The AppSheet Data Locale must match the Google Sheets Locale. This ensures that your application reads and writes Date, DateTime, Decimal, Percent, Price (Currency), and Time values to the Google sheet in the proper locale format.

When you add a new table to your application using the app editor, AppSheet automatically retrieves the Locale setting from the Google worksheet and sets the table's Data Locale setting appropriately.

If you later change the Google Sheets Locale setting, AppSheet automatically retrieves the new setting from the worksheet and sets the table's Data Locale setting appropriately the next time you open the app in the app editor.

Configure the locale

To configure the locale:

1. Make sure that your Google Sheet specifies the appropriate locale. From the Google Sheets File menu, select Spreadsheet settings. In the Settings dialog, set Locale to your locale. For example, in Thailand select Thailand.
   
   
2. Make sure that each Currency, Date, DateTime, Number, Percent, and Time value in the Google Sheet is formatted appropriately. Do this by selecting all of the cells in the column containing the data values. From the Format menu, select Number and then the appropriate formatting style. For example, for date values, select Date, for currency values, select Currency, for time values, select Time, and so forth. Do this for each Currency, Date, DateTime, Number, Percent, and Time column.
3. Add the Google worksheet as a table using the app editor. AppSheet will automatically set the table's locale to match the Google worksheet's locale. If you later change the Google worksheet Locale setting, AppSheet will automatically set the table's locale to match the Google worksheet when you next open the application in the editor.
   
   
    
4. Make sure that your browser or device is set to use your locale. For example, in the United Kingdom, select the UK locale. In Thailand, select the Thai locale. The browser or device setting completely determines how data values are displayed within the app running on your browser or device. For information about setting the locale on a Chrome browser, see Change Chrome languages and translate web pages.
5. If you use a calendar other than the Gregorian calendar, make sure that your browser or device is set to use that calendar. For example, in Thailand, select the Buddhist calendar. Many countries use the Gregorian calendar, so in many cases you can skip this step.
6. Click Sync in the app to read the latest values from the Google Sheet. See if the Date, DateTime, Decimal, Percent, Price, and Time values are displayed correctly in the app. If not, verify your browser or device locale settings.
7. Try updating a Date, DateTime, Decimal, Percent, Price, and Time value and saving the changes to the server. See if the correct values appear in the Google Sheet and the app.
8. All data is sent between the app and the AppSheet server in a common universal format. This makes it easier for the app and server to communicate. It has no effect on how data is stored in the worksheet or displayed in the client. 

About the compatibility locale

One of the values appearing in the Data locale drop-down is the Compatibility locale. This value is present for backward compatibility only. It preserves AppSheet’s old, limited locale behavior. If you choose Compatibility locale, AppSheet uses a period as the decimal separator between the whole and fractional parts of Decimal, Percent, and Price values. AppSheet uses simple rules for saving Date, DateTime, and Time values. We save formulas in the United States locale format, which works for many locales that use a period for the decimal separator.

If your Google Sheet does not specify a Locale, AppSheet sets the AppSheet Data locale to Compatibility locale. However, we strongly recommend you specify a Google Sheet Locale.

We currently support approximately 70 Locale values. We selected these locales based upon the locales that Google Sheets currently supports. Contact Support if a locale you need is missing from AppSheet.

Locale for Excel

It is not necessary to set the AppSheet locale for apps that store data in Excel files on Box, Dropbox, Google Drive, Office 365, or OneDrive. This is a consequence of the way we add and update data and formula values in Excel files. The AppSheet Data locale should be set to either United States or Compatibility.

Locale for Smartsheet

It is not necessary to set the AppSheet locale for apps that store data in Smartsheet. This is a consequence of the way AppSheet adds and updates data and formula values in Smartsheet. The AppSheet Data locale should be set to either English (United States) or Compatibility.

If your app involves workflow rules that send emails or SMS messages, we use the locale of your table/sheet to determine how to format the values (like dates and times) in the message body. In this case, it is important to set the locale of your Smartsheet appropriately.
