Crate sheeter_engine 

Sheeter is a data file conversion library and CLI tool.

This crate provides functions to convert between CSV and JSON formats. It is designed to be small, fast, and portable, suitable for use on low-end devices such as Android phones. The core idea is simple: take data in one format, understand its structure, and emit it in another format without unnecessary overhead.

Examples

Convert CSV to JSON:

use sheeter_engine::csv_to_json;

let csv = "name,age\nAlice,30\nBob,25";
let json = csv_to_json(csv).unwrap();
assert_eq!(json, r#"[{"name":"Alice","age":"30"},{"name":"Bob","age":"25"}]"#);

Convert JSON to CSV:

use sheeter_engine::json_to_csv;

let json = r#"[{"name":"Alice","age":"30"},{"name":"Bob","age":"25"}]"#;
let csv = json_to_csv(json).unwrap();
assert_eq!(csv, "name,age\nAlice,30\nBob,25\n");

Modules

canonical

detect

filter

inspect

ndjson

query

SQL query engine over files.

sort

transform

view

Table rendering and multi-source loading for sheeter view.

xlsx_tools

Excel-specific helpers: xlsx:merge and xlsx:frag.

Enums

Functions

convert

Converts input from one format to another via the canonical hub.

convert_workbook

Converts a byte buffer between formats, supporting multi-sheet workbooks.

convert_workbook_with_options

Like convert_workbook, but lets the caller pick the SQL dialect and the table name used when writing SQL output.

csv_to_json

Converts a CSV string into a JSON array of objects.

csv_to_toml

Converts CSV to TOML via the canonical hub.

csv_to_tsv

Converts CSV to TSV by composing csv_to_json and json_to_tsv.

csv_to_xml

Converts CSV to XML via the canonical hub.

json_to_yaml

Converts a JSON array of objects into a YAML sequence of mappings.

stream_delimited

Converts CSV or TSV input to CSV or TSV output using constant memory.

toml_to_csv

Type Aliases

OutputDoc

One output document: (sheet_name, bytes). Returned by convert_workbook because multi-sheet inputs can produce more than one output.
