Which export formats should a writing app support?

These five formats form a solid foundation because each serves a distinct purpose. Markdown is the lingua franca of plain-text writing, easily converted to other formats. HTML is the language of the web, ready for blogging or websites. Plain text is the lowest common denominator, readable on any device. PDF locks in visual layout for print or formal sharing. JSON preserves the complete structure of your document, including metadata, for backup or migration.

• Markdown – lightweight, human-readable, and widely supported by editors and static site generators.
• HTML – ready for web publishing with minimal conversion.
• Plain text – universal and future-proof, though it loses formatting.
• PDF – fixed-layout for printing or sharing with non-editors.
• JSON – retains the full document model, ideal for archiving or transferring between apps.

An app like NeoGlint, a minimal offline-first Markdown editor, supports all five of these formats, ensuring your writing remains accessible and portable. NeoGlint stores each Space as a plain JSON file on your disk, and you can export to Markdown, HTML, JSON, plain text, and PDF at any time.

Markdown has become the de facto standard for plain-text writing because it's both human-readable and machine-parsable. When an app exports to Markdown, it ensures your work isn't trapped in a proprietary database. You can move your content to another editor, publish it on a static site, or simply archive it knowing it will be readable decades from now.

Furthermore, Markdown serves as a universal source format. Many writing apps, including NeoGlint, use Markdown as their native storage or export format. NeoGlint round-trips cleanly between Markdown and rich text, so what you type is what gets saved. This means you can switch between apps without losing formatting.

• Portability – open your files in any text editor, on any platform.
• Future-proofing – plain text outlasts proprietary formats.
• Interoperability – import into other Markdown editors, static site generators, or note-taking tools.
• No lock-in – you own your content, not the app.

When evaluating a writing app, check that its Markdown export produces clean, standard Markdown, not a proprietary dialect. NeoGlint exports standard Markdown that is fully compatible with other Markdown editors.

PDF export is essential when you need to share a document with someone who doesn't have your writing app or when you want to ensure the layout remains consistent across devices. It's the standard for reports, manuscripts, and any document intended for print or professional presentation. HTML export, on the other hand, is key for bloggers, web writers, and anyone publishing online. It allows you to paste content directly into a website or content management system without reformatting.

While not every writer needs both, having them available makes an app more versatile. NeoGlint includes PDF and HTML export among its supported formats, alongside Markdown, plain text, and JSON. This ensures that whether you're submitting a manuscript or publishing a blog post, you can get your writing out in the right format.

When assessing an app, consider whether its PDF and HTML exports preserve your formatting accurately. NeoGlint's PDF export uses standard PDF fonts via pdf-lib, ensuring reliable rendering.

Plain text is the most basic yet most durable format. It strips away all formatting but guarantees that your words can be read on any device, from a modern computer to a vintage terminal. This is invaluable for archival purposes or when you need to share content with someone using a different system. JSON, on the other hand, is a structured data format that captures the entire state of your document, including headings, lists, and other formatting details. It's not meant for reading but for machine processing, making it ideal for backups or for importing into another application that understands the same schema.

For writers, plain text export is a safety net: if all else fails, your words remain. JSON export is a fidelity net: if you need to move to a new app, you can bring your structure along. Some apps, like NeoGlint, use JSON as their native storage format, meaning every Space is already a JSON file on your disk. This makes JSON export essentially a copy of the original file, ensuring perfect fidelity.

• Plain text – universal, future-proof, but loses formatting.
• JSON – preserves structure, ideal for backup and migration.

When evaluating an app, check that plain text export doesn't introduce unwanted characters or truncate content, and that JSON export includes all metadata. NeoGlint's JSON export is a direct representation of the Space file, so nothing is lost.

While the core five formats cover the majority of writing needs, some writers require specialized formats. DOCX is the standard for word processing and is often requested by publishers, editors, or collaborators who use Microsoft Word. EPUB is the standard for e-books and is essential if you plan to self-publish on platforms like Amazon Kindle or Apple Books.

However, supporting these formats adds development overhead and can introduce compatibility issues. For many writing apps, especially minimal ones, focusing on the core formats is a deliberate choice to keep the software fast and reliable. NeoGlint, for instance, does not currently support DOCX or EPUB export; it prioritizes the formats that cover the most common needs without bloating the application. If you need DOCX, you can often convert from Markdown or HTML using other tools.

Before choosing an app based on these formats, consider whether you truly need them. If you occasionally need DOCX, a converter might suffice. If you're publishing an e-book, EPUB support could be a deciding factor.

To assess export capabilities, start by exporting a sample document with varied formatting—headings, lists, bold text, links—and inspect the output in each format. For Markdown and HTML, check that the syntax is standard and not proprietary. For PDF, verify that the layout matches your expectations. For JSON, ensure it's valid and contains all your content. Also, test importing the exported file back into the app or into another tool to confirm round-trip fidelity.

Another key factor is where your files are stored. Some apps keep your content in a proprietary database, making export the only way to access your work. Others, like NeoGlint, store each Space as a plain JSON file on your disk, so you always have direct access to your data. This local-first approach means you're not dependent on export for backup; you can simply copy the files. NeoGlint also provides export to all five core formats for convenience and sharing.

• Test with varied content – include headings, lists, links, and images.
• Check for standard compliance – avoid proprietary extensions.
• Verify round-trip – export, then re-import to ensure fidelity.
• Consider storage model – local files are more transparent than databases.

Finally, read the app's documentation or FAQ to see what formats are supported and any limitations. A transparent app will state clearly what it does and doesn't do.
