About JSON files

JSON (JavaScript Object Notation) describes data as objects, arrays, strings, numbers, booleans and null, and nothing else. It has no date type, no comments and no trailing commas. Each of those gaps causes errors every day.

The rules are stricter than most people remember. Keys must be double-quoted strings; single quotes are not allowed anywhere; a comma after the last item of an object or array is invalid even though most languages permit it. The invalid sample here breaks exactly those rules, one per line.

JSON has no date type, so by convention dates travel as strings. Most use ISO 8601, as this sample does. That means a date in JSON is only as reliable as the agreement between whoever wrote it and whoever reads it.

For developers: exact bytes and SHA-256

Sizes are decimal (1 MB = 1,000,000 bytes). The hosted files never change between builds, so these checksums stay valid.
