CSV Modern Codeblock

CSV Modern Codeblock renders csv and tsv fenced code blocks as interactive tables inside Obsidian.

Now (since v1.1.0) with EDIT support.

This plugin was rewritten from scratch for modern table UX, stricter CSV handling, and better behavior with data-heavy notes. It was inspired by the original CSV Codeblock idea, but it is not a fork.

Original project that inspired the concept: https://github.com/elrindir/obsidian-csv-codeblock

Why This Plugin Exists

Markdown tables are tedious when the data is large, frequently edited, copied from spreadsheets, or full of long text. CSV and TSV are much easier to write, paste, diff, and maintain in source form. This plugin keeps that convenient source format while rendering it as a much more usable table in preview.

Features

• Renders csv and tsv code blocks as tables directly in notes
• Uses the first row as the header by default
• Supports quoted fields, escaped quotes, quoted commas, multiline quoted cells, trailing empty cells, and CRLF line endings
• Auto-detects comma and semicolon delimiters for csv blocks
• Reports malformed CSV with a clear explanation that includes row, field, and line information
• Detects http, https, and mailto values and renders them as links
• Keeps header rows sticky by default
• Uses a vertically scrollable table area for tall datasets
• Adds a toolbar with optional controls for sorting, per-column filtering, compact mode, zebra striping, high-table mode, and single-cell editing
• Buffers edited cells during Edit mode and writes them back to the source fenced code block in one save
• Supports per-codeblock options for title, layout, filtering, sorting, links, delimiter selection, and height

Performance And Implementation Improvements

Compared with the earlier plugin idea, this rewrite adds:

• A real CSV parser instead of splitting rows on delimiters
• Correct handling of escaped and quoted fields
• Delimiter autodetection for semicolon-separated CSV exports
• Stronger malformed-input validation instead of silently rendering broken tables
• Direct row rendering without building a separate full parsed matrix first
• Lower memory pressure for large tables
• A dedicated stylesheet for table presentation and theme integration

Default Behavior

• The first row is treated as the header
• Sticky headers are enabled
• A base vertical scroll area is enabled
• Sorting is off until you press Sorting
• Per-column filtering is off until you press Filtering
• Compact mode is off until you press Compact
• Zebra striping is off until you press Zebra
• High-table mode is off until you press High table
• Cell editing is off until you press Edit mode

Basic Usage

```csv
Name,Role,City
Alice,Researcher,Berlin
Bob,Editor,Paris
```

TSV works the same way:

```tsv
Name	Role	City
Alice	Researcher	Berlin
Bob	Editor	Paris
```

Toolbar Controls

Each rendered table includes a toolbar above it:

• Sorting enables sorting by clicking header cells
• Filtering shows a filter input under each header column
• Compact switches to fit-to-width mode
• Zebra toggles alternating row striping
• High table doubles the vertical scroll height
• Edit mode enables single-click cell editing

These controls change only the rendered view. They do not modify your source data.

Edit mode is the exception: when it is enabled, clicking a table cell opens an inline editor. Leaving the editor or pressing Ctrl+Enter / Cmd+Enter applies that cell to the rendered table without writing the Markdown file yet. Press Escape to cancel the active cell edit. When there are buffered changes, the Edit mode button shows *. Press Edit mode again to write all buffered changes back to the fenced code block in one save. Sorting and filtering can stay enabled; edited rows are mapped back to their original CSV row before saving.

Codeblock Options

You can set per-table defaults directly on the opening fence line:

```csv title:"Folktales" sort:true filter:true compact:true zebra:true high-table:true edit:true
Nr.;Titel;Quelle
1;Der Froschkönig;https://projekt-gutenberg.org/
```

Supported options:

• title:"..."
• header:true|false
• sticky:true|false
• sort:true|false
• filter:true|false
• compact:true|false
• zebra:true|false
• high-table:true|false
• edit:true|false
• links:true|false
• delimiter:auto|comma|semicolon|tab
• max-height:<css-size>

Examples:

• delimiter:semicolon
• max-height:32rem
• compact:true
• filter:true

Submission And Privacy Disclosures

• No network requests
• No telemetry, analytics, ads, or tracking
• No accounts, subscriptions, or payments
• No external services
• No access to files outside normal Obsidian plugin execution and rendered note content
• Fully local behavior inside Obsidian
• Open source

Development

The source code lives in src/main.ts. The root main.js file is generated and is intentionally not tracked in Git.

npm ci
npm run lint
npm run build

npm run build generates the release main.js artifact from the TypeScript source.

Releasing

For Obsidian community submission, create releases from GitHub Actions so release assets get GitHub artifact attestations.

1. Bump manifest.json, versions.json, and package.json.
2. Commit the source changes.
3. Tag the commit with the exact manifest version, for example 1.1.1.
4. Push the commit and tag.

The .github/workflows/release.yml workflow builds main.js, attests main.js, manifest.json, and styles.css, then uploads those files to the GitHub release.

Inspiration

CSV Modern Codeblock was inspired by the original CSV Codeblock plugin:

This project is a separate rewrite with a new codebase, different implementation, added validation, performance-focused parsing changes, and expanded table functionality.
