Data & Formats

Typed columns and a frozen header row, so it opens as a usable sheet rather than raw text.

Delimiters are detected, headers are used as keys, and numbers become numbers rather than strings.

Pick the columns you want, reorder them, drop the rest, and change the delimiter on the way out.

One sheet or every sheet, as plain CSV that any tool can read.

Turn a deeply nested object into flat dotted paths, or put a flat one back together.

Pretty-print it to read, minify it to ship, or sort the keys so two files can be compared.

An array of objects becomes a table, with nested values flattened into dotted column names.

Readable block style by default, or compact flow style if it is going into a config field.

Find out exactly where a document breaks, with the line and column, instead of a bare parse error.

Attributes and text nodes are given predictable names, so the output is something you can index into.

Safe parsing only — no custom tags, no object construction, nothing that can execute.
