TSV → JSON — developer guide

TSV → JSON converter with the same privacy guarantees as other FastMinify tools.

Developer notes

• Validate inputs upstream. • Reverse conversions may be lossy depending on format. • Large files: prefer desktop browsers.

Use cases

• Quick prototyping between formats. • Lightweight CI pipelines without middleware. • Config review before commit.

About these options

CSV exports: choose a delimiter (Auto follows locale — semicolon on /fr), RFC-minimal vs always-quoted fields, line endings, and whether to emit a header row. CSV imports: delimiter + whether row 1 holds column names (Auto delimiter follows locale only for convenience). JSON output (XML, YAML, or CSV sources): indentation (including compact one-line) and optional recursive key sort. JSON → XML: toggle pretty-printing and indent width. YAML output: indent width, readable vs tighter layout, and deterministic string quoting (there is no source YAML file to “preserve”). XML comments are not represented in the intermediate JSON tree.

Examples

Basic example

Input

id	sku	tier	active	region	owner

FM-002	silver	false	us-east	sam
FM-003	trial	true	ap-south	alex
FM-004	enterprise	true	eu-central	nina

Output

[
  {
    "id": "1",
    "sku": "FM-001",
    "tier": "gold",
    "active": "true",
    "region": "eu-west",
    "owner": "julien"
  },
  {
    "id": "2",
    "sku": "FM-002",
    "tier": "silver",
    "active": "false",
    "region": "us-east",
    "owner": "sam"
  },
  {
    "id": "3",
    "sku": "FM-003",
    "tier": "trial",
    "active": "true",
    "region": "ap-south",
    "owner": "alex"
  },
  {
    "id": "4",
    "sku": "FM-004",
    "tier": "enterprise",
    "active": "true",
    "region": "eu-central",
    "owner": "nina"
  }
]

Second example

Input
