Translate months in data files

support
1

Is there a way to parse months in a data file and translate them automatically? Or the only way is to use i18n?

[
    {
        "Year": "2025",
        "Month": "April",
        "Amount": "6,164"
    },
    {
        "Year": "2025",
        "Month": "March",
        "Amount": "4,164"
    },
    {
        "Year": "2025",
        "Month": "February",
        "Amount": "3,164"
    },
    {
        "Year": "2025",
        "Month": "January",
        "Amount": "2,164"
    }
]

Create a parsable date string using the first three letters of the month name, then use the time.Format function to localize:

{{ range site.Data.foo }}
  {{ $t := time.AsTime (fmt.Printf "01 %s %s" (strings.Substr .Month 0 3 | strings.ToLower) .Year) }}
  {{ $t | time.Format "January 2006" }}
{{ end }}

Our documentation lists the most common parsable date strings. Here is the complete list:

Is {{ $t | time.Format "January" }} valid? I just need the month. It works in my test though.

Yes. Use one or more of these components in your layout string:

Thank you. Your solution saved me from duplicating multiple data files. I will try to consolidate those I had created in the data folder into a single file in page bundles.
