Large files

Open huge files and start working.

Inkline is built to keep multi-million-line JSON, JSONL, logs, exports, and generated text usable. Open, search, scroll, and edit without waiting for a heavyweight IDE to process the entire file first.

Formatting

Format large files without turning them into a side project.

Pretty-print or minify structured data from the editor. Inkline handles the large API responses, generated exports, and compact logs that are awkward to inspect in a browser tool or a general-purpose IDE.

Large-file editing

Open and navigate files with millions of lines while the editor keeps the document responsive.

Formatting that scales

Format JSON, JSONL, XML, HTML, CSS, and SQL without moving the contents into another app.

Syntax highlighting

19 bundled languages, with more available as extensions.

C, C++, C#, CSS, CSV, Go, Java, JavaScript, JSON, Kotlin, Markdown, PHP, Rust, Shell, Swift, TOML, TypeScript, XML, and YAML are ready when you install Inkline.

Zed-compatible language extensions

Add more syntax definitions when a project uses a language outside the bundled set.

Terminal

Run commands beside the file you are editing.

Inspect generated files, run project commands, and verify structured data while the active editor remains visible.

Split editor

Keep related files visible together.

Open two editors side by side when a change crosses files, when source needs a reference, or when structured data needs a second view.

Regex

Build and test expressions beside your files.

Test patterns, flags, and replacement text without moving content into a separate browser tool or losing the project context around it.

Diff

Compare text without leaving the workspace.

Paste or load two versions, choose the comparison mode, and inspect additions and removals in a focused side-by-side tool.

QR Code

Turn text into a QR code locally.

Generate a QR code, adjust its correction level, save it as an image, or copy the result directly from Inkline.

Choose a source file and target format, inspect the result, and keep common conversion work next to the editor and project browser.

Text Tools

78 useful commands, right where you edit.

Clean pasted data, reshape files, and fix common formatting problems without writing a one-off script.

Lines and whitespace

Structured data

Pretty-print or minify JSON and XML, convert JSON Lines to arrays, and format HTML, CSS, and SQL.

Data conversion

Move between CSV, TSV, JSON, dotenv, Java properties, and query strings while keeping the result in the editor.

Text Tools

Encode, verify, and generate without leaving the file.

Use the current selection as input and place the result straight back into your document.

Encoding

Encode and decode Base64, Base64URL, JWT, URLs, HTML entities, JSON strings, and hex.

Hashes and inspection

Generate MD5, SHA-1, and SHA-256 hashes, inspect Unicode, and create file-integrity reports.

Everyday generators

Create UUIDs, convert dates and epochs, change identifier casing, inspect number bases, count text, and generate slugs.
