Not really related to this particular PR, but I see IllegalArgumentExceptions thrown all over the place for null arguments. There are points for and against using IllegalArgumentException instead of NullPointerException. When using NPE, we could simply use Objects.requireNonNull(currency) or Objects.requireNonNull(currency, "Currency code should not be null").

If we use IAE instead, we should add such a utility method in the codebase so this becomes:

    public void setCurrencyCode(String currency) {
        checkParameterNonNull(currency, "Currency code must not be nulll");
        ...
    }

Or use JSpecify anntotations (that makes the user's IDE, Spotbugs and other tools emit warnings) and possibly use a tool such as cabe to automatically have those checks injected during compilation based on the annotations (note: as the author of Cabe, I'm naturally biased here ).

This would simply look like this:

@NullMarked
class OdfTableCell {
    ...
    // as the whole class is @Nullmarked, currency must not be null
    // the user's IDE (if correctly configured) will warn about a (possibly) null value
    public void setCurrencyCode(String currency) { 
        ...
    }
}

Only where null is allowed, the parameter has to be annotated with @Nullable.

throw new IllegalArgumentException("Currency code of cell should not be null.");
}

I don't think this is an improvement: the old code would throw an exception, the new code more or less silently returns null. Further down, this may lead to incorrect results. Better throw an exception. If the user wants to handle this leniently, they should catch the exception.
If on the other hand empty cells with time value type should be allowed, we should return an Optional instead. Are empty time cells allowed in ODF? I don't know.

You used the german format with a day-of-year and week-based-year here. I think this should be d. MMM yy. The old code used the american format. Which one to use depends on the input spreadsheet and maybe the locale setting, but I have to check the spreadsheet first.

I first thought that ODF handles this differently, and we'd have to convert the format strings. But OdfNumberDateStyle explicitly mentions the SimpleDateFormat format string, which uses the same format as DateTimeFormatter. So we really need to use the lowercase letters for times. The list of symbols is given in the OdfNumberDateStyle Javadoc.

The LibreOffice Strings are all locale dependent. If we want to use the LibreOffice strings directly, a translation method has to be implemented with lookups for all supported locales. I think, internally, the ISO 8601 format should be used and a translation method if the library user wants to use the LibreOffice format strings (which as I understand it are not part of the ODF spec).

I think we should maybe add additional String toLibreOfficeFormat(String isoFormat, Locale locale) and String parseLibreOfficeFormat(String loFormat, Locale locale) as convenience methods for users. To have localized meanings when calling setFormatString() is a nightmare when you want to develop an application that should be able to run on different locales.

The LibreOffice Strings are all locale dependent.

AFAIK LibreOffice displays locale dependent stuff in the UI but always stores it as en-US (i.e. effectively locale-independent) in ODF.

(in contrast, i've had to solve problems related to importing locale-dependent text fields from DOCX....)

Yes, so the formatting code needs some updates. I think it would be a good thing to support the (english) LibreOffice format strings as well as the ISO format, using two different methods. I see if I can put together a two-way-converter building on what is already there and make a suggestion in code (PR).
That way, compatibility for existing users is maintained and we also have a more "standard" (from the Java perspective) way of dealing with formats. Ideally, this will cover all formats, but I'll start with dates and times.

The format string contains a date part, so the value should contain a date as well. And in the format string, lowercase letters have to be used for the time part.
