Before You Publish a File Called copy.json
Start by identifying who will read the file. An editor needs understandable labels and context; an application needs stable keys and predictable value types. If both use the same document, write down the structure so neither has to infer it from the current contents.
Choose fields according to their role. A page heading, a navigation label, and an error message may all be strings, but they serve different purposes. Keep those distinctions visible in the key names. Decide whether empty strings are allowed and what should happen when an expected entry is missing.
Validate syntax separately from content. JSON requires double-quoted strings and does not allow comments or trailing commas. A parser can catch those errors, while a schema can check required fields and value types. Neither check tells you whether a sentence is accurate, readable, or suitable for its position on the page.
Choose a location based on a documented requirement, not the familiarity of a directory name. The .well-known directory has defined uses, and placing an arbitrary copy.json file there does not create a shared standard. For ordinary website text, a clearly documented project location may be more appropriate.
Finally, decide how updates will reach the people and software using the file. Renaming a key can break a consumer even when the wording itself has barely changed. Review structural edits separately from copy edits, keep a change history, and avoid putting private notes or credentials in any publicly accessible file.
