Example: TOML input and real CSV output
The output below was generated by the same conversion code the converter uses, run on this sample when the page was built.
[package]
name = "invoice-tool"
version = "0.3.2"
edition = "2021"
[dependencies]
serde = "1.0"
tokio = "1.40"
[profile.release]
lto = true
opt-level = 3A TOML document always parses to a table (an object), and CSV output needs a root-level array of objects, so the converter stops with "CSV output requires an array of objects".
Workaround: convert to JSON first (TOML to JSON), reshape the data there, then use JSON to CSV.
The same data is 165 characters as minified JSON and 244 as pretty-printed JSON. Sizes are character counts, not tokens: token counts depend on the model's tokenizer (see the tokenizer comparison).
TOML to CSV: what changes
- Reading TOML: A TOML document always parses to a table (an object), never a bare array. Datetimes are a TOML-native type and come out as ISO 8601 strings.
- Writing CSV: CSV output needs a root-level array of flat objects; anything else fails with "CSV output requires an array of objects". Nested objects are not flattened, so extract or flatten them first.
