slate is a local tool for creating, organizing and exporting csv tabular data directly in your browser.
No internet connection or installation required — just download the html file and it will open as a web page.

Built for people who need a lightweight and local way to manage personal structured data without external dependencies. Ideal for those who prefer simplicity, privacy and control. Not for highly specific professional use but some edge-cases are covered.

All your data stays on your machine without accounts, servers or sync. Just remember to export frequently and before deleting browser data.

slate is stable and functional, aimed at staying minimal: just open the latest html released and start working.

• Import/export: Bring and keep your data in a future proof plain text format (csv with any separator).
• Record editing: View, modify and organize entries with ease, including bulk delete and fuzzy search.
• Autofill categories: Tag any column as a category to create autofill buttons for every entry under it.
• Date formats: Configurable date input with custom format selector and optional autofill with current date.
• Storage: Everything is saved in-browser using the built in localstorage and can be easily exported.
• Field types: Define columns with custom field types like text, number, date or boolean.
• Hiper-light: Compatible with virtually any modern browser including mobile, at just ~100KB.

Remember that your data stays in the browser until you export it! - back it up regularly if needed.
