Two applications can both open a file and still understand it differently. A date, a color, or a formatted paragraph may carry assumptions that are not obvious in the interface. Compatibility depends on what the tools agree to preserve.
A shared specification gives those assumptions a place to be described. Real implementations may still support different parts of it, or interpret optional details in different ways. A successful import therefore deserves a closer look than a success message alone.
Use a small sample with the features your work relies on. Move it between the tools and inspect the result. Practical interoperability is a behavior you can verify, rather than a word on a feature list.
- Choose a representative sample.
- Check important details after import.
- Read the supported-format notes.
Picture this situation.
Consider a calendar exported from one application and opened in another. Agreement about dates and fields matters as much as whether the file transfers successfully.
A second way to look.
Follow the information through one complete task. What is created, where does it go, and what will someone need to understand it later?
