To edit the template on your local computer:

Upload the edited template file from your computer to your data source.

For example, to download the template file from Google Drive to your computer:

Download the template file to your computer.
For example, if you are using the Google Chrome browser:
1. Download the template file to your computer by clicking the Download button at the top right of the browser screen.
2. You will see the downloaded file in the bottom left of the browser screen. Click ^ to the right of the downloaded template name and select Show in Finder.

Click the folder name link to the right of the Location property to open the Google Drive folder containing the template file.
Drag and drop the updated template file from the folder on your computer to the Content folder on Google Drive. The template file will retain its original DocId on Google Drive.

Manually create a JSON template

Manually create a JSON template file by creating an empty text file, entering valid JSON, and saving the file using an .json extension.

The following provides an example JSON file:

{
  "MyTable": [
  <<Start: Select(MyTable[MyKey], TRUE)>>
      {
         "UpdateMode": "<<_UPDATEMODE>>",
         "Application": "<<_APPNAME>>,
         "TableName": "<<_TABLENAME>>,
         "UserName": "<<_USERNAME>>,
         "LastName": "<<[LastName]>>",
         "FirstName": "<<[FirstName]>>",
         "Age": "<<[Age]>>",
         "Computed Total": "<<[Qty]*[Price]>>",
         "ComputedName": "<<_ComputedName>>"
      },
   <<End>>
   ]
}

After the template file is saved to your computer, upload it to one of the data sources described in Configure the data sources for storing templates.

For example, you can upload the template file to Google Drive, as follows.

Ensure that the Convert uploaded files to Google Docs editor format option is disabled as described in Upload .txt templates to Google Drive.
Open Google Drive and navigate to the Google Drive folder where you wish to upload the file.
Click New and then click File upload.
When the file open dialog appears, navigate to the template file on your computer, select the file, and click Open.

After the template file is uploaded, us it as described in Use an existing template.

Each time you modify the JSON template you must upload the template file to Google Drive. Google Drive will retain the original DocId. AppSheet will use the last uploaded version of the template file as the attachment template.
