Is this the full TOML specification?

No. It is a quick reference for everyday syntax. See the TOML v1.0 guide for more context.

Can I validate these examples?

Yes. Use Copy or Try in formatter — parsing stays in your browser.

Reference

A scannable TOML v1.0 syntax reference: keys, strings, numbers, dates, tables, and arrays. Copy an example or open it in the formatter.

Bare keys, quoted keys, and dotted keys. Dotted keys create nested tables without a [header].

.toml

name = "demo"
"quoted key" = true
physical.color = "orange"
physical.shape = "round"

Basic strings support escapes. Literal strings keep backslashes. Triple quotes allow multiline text.

.toml

basic = "Hello\nWorld"
literal = 'C:\Users\demo'
multi = """
First line
Second line
"""

Integers (including hex/oct/bin), floats, underscores for readability, plus inf and nan.

.toml

int1 = 99
int2 = 1_000_000
hex = 0xDEADBEEF
float1 = 3.1415
inf = inf
not_a_number = nan

Only lowercase true and false.

.toml

enabled = true
debug = false

Offset datetime, local datetime, local date, and local time are first-class types.

.toml

odt = 1979-05-27T07:32:00Z
ldt = 1979-05-27T07:32:00
ld = 1979-05-27
lt = 07:32:00

Arrays are [ … ]. Values of different types in one array are allowed by the language but often discouraged in configs.

.toml

ports = [ 8001, 8001, 8002 ]
mixed_ok = [ 1, 2, 3 ]
nested = [ [ 1, 2 ], [3, 4, 5] ]

[table] headers define nested maps. Subtables use dotted names like [server.tls].

.toml

[server]
host = "127.0.0.1"
port = 8080

[server.tls]
enabled = true

[[name]] appends a table to an array. Repeat the header for each element.

.toml

[[products]]
name = "Hammer"
sku = 1

[[products]]
name = "Nail"
sku = 2

Compact tables written as { key = value, … } on one line. Good for small nested objects.

.toml

point = { x = 1, y = 2 }
name = { first = "Tom", last = "Preston-Werner" }

Comments start with #. A parse→stringify format pass drops them — the formatter warns about that.

.toml

# Full-line comment
key = "value"  # trailing comment
