Just for fun, I did a search right now on Google for a few file ODF and MS Office based formats (not to be mistaken for ISO or ECMA OOXML), to get an idea of their relative usage. I searched using 'filetype:odt' and equvalent terms, and got these results:
| Type | ODF | MS Office |
|---|---|---|
| Tekst | odt:282000 | docx:308000 |
| Presentasjon | odp:75600 | pptx:183000 |
| Regneark | ods:26500 | xlsx:145000 |
Next, I added a 'site:no' limit to get the numbers for Norway, and got these numbers:
| Type | ODF | MS Office |
|---|---|---|
| Tekst | odt:2480 | docx:4460 |
| Presentasjon | odp:299 | pptx:741 |
| Regneark | ods:187 | xlsx:372 |
I wonder how these numbers change over time.
I am aware of Google returning different results and numbers based on where the search is done, so I guess these numbers will differ if they are conduced in another country. Because of this, I did the same search from a machine in California, USA, a few minutes after the search done from a machine here in Norway.
| Type | ODF | MS Office |
|---|---|---|
| Tekst | odt:129000 | docx:308000 |
| Presentasjon | odp:44200 | pptx:93900 |
| Regneark | ods:26500 | xlsx:82400 |
And with 'site:no':
| Type | ODF | MS Office |
|---|---|---|
| Tekst | odt:2480 | docx:3410 |
| Presentasjon | odp:175 | pptx:604 |
| Regneark | ods:186 | xlsx:296 |
Interesting difference, not sure what to conclude from these numbers.
