json-to-usv

Convert JavaScript Object Notation (JSON) to Unicode Separated Values (USV). Built with the USV Rust crate.

Syntax:

stdin | json-to-usv [options] | stdout

Example:

cat example.json | json-to-usv

More examples below.

Options

Options for USV separators and modifiers:

• -u, --us : Set the unit separator (US) string.

• -r, --rs : Set the record separator (RS) string.

• -g, --gs : Set the group separator (GS) string.

• -f, --fs : Set the file separator (FS) string.

• -e, --esc : Set the escape (ESC) string.

• -z, --eot : Set the end of transmission (EOT) string.

Options for USV style:

• --style-braces : Set the style to use braces, such as "{US}" for Unit Separator.

• --style-controls : Set the style to use controls, such as "\u001F" for Unit Separator.

• --style-symbols : Set the style to use symbols, such as "␟" for Unit Separator.

Options for USV layout:

• --layout-0: Show each item with no line around it. This is no layout, in other words one long line.

• --layout-1: Show each item with one line around it. This is like single-space lines for long form text.

• --layout-2: Show each item with two lines around it. This is like double-space lines for long form text.

• --layout-units: Show each unit on one line. This can be helpful for line-oriented tools.

• --layout-records: Show each record on one line. This is like a typical spreadsheet sheet export.

• --layout-groups: Show each group on one line. This can be helpful for folio-oriented tools.

• --layout-files: Show one file on one line. This can be helpful for archive-oriented tools.

Options for command line tools:

• -h, --help : Print help

• -V, --version : Print version

• -v, --verbose... : Set the verbosity level: 0=none, 1=error, 2=warn, 3=info, 4=debug, 5=trace. Example: --verbose …

• --test : Print test output for debugging, verifying, tracing, and the like. Example: --test

Example

Suppose file example.json contains:

[
    ["a","b"],
    ["d","e"]
]

Run:

Output:

a␟b␟␞
c␟d␟␞

FAQ

What converters are available?

• asv-to-usv & usv-to-asv

• csv-to-usv & usv-to-csv

• json-to-usv & usv-to-json

• xlsx-to-usv & usv-to-xlsx

When to use this command?

Use this command when you want to convert from JSON to USV.

A typical use case is when you have JSON data, such as a web request result, and you want to convert it to USV, such as to make the data easier to view, or edit, or maintain.

Our real-world use case is converting a bunch of JSON web API RPC results from a variety of programs, including Excel, to USV so we're better-able to handle quoting, and multi-line data units, and Unicode characters in a wide variety of human languages.

Why use USV instead of JSON?

See the documentation for USV.

Is USV aiming to become a standard?

Yes, USV is submitted to IETF.org as an Internet-Draft work in progress: link.

Can I build my own USV tools?

Yes, and you may freely use the USV RFC and USV Rust crate.
