Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna

Grayslate v0.4.0

👉 A fast, free developer scratchpad for working with code, data, text and large files.

Grayslate is a free and open source, cross-platform developer scratchpad designed for the small jobs that come up while coding or working with data. Paste an API response, inspect JSON, explore a large CSV, transform or encode text, preview Markdown, work with code snippets or simply capture a quick thought. Grayslate recognizes the content you are working with and puts appropriate transformations at your fingertips. New slates are automatically given useful names and extensions, saved locally as you type and made searchable for later use. Files opened from elsewhere on your computer are only changed when you explicitly save them. All transformations run locally, with no account, cloud upload or telemetry required.



Features:
• Automatically recognizes pasted or opened content and suggests relevant transformations
• Includes more than 80 built-in transformations for code, data and text
• Recognizes more than 40 programming, markup and data languages/formats from file extensions, shebangs or content
• Automatically names new slates, chooses useful file extensions and saves them locally as you type
• Browse recent slates or search saved slates by name and content
• Opens text and CSV files up to 200 MB
• Rust-backed, virtualized CSV table handles files containing hundreds of thousands of rows while keeping scrolling responsive
• JSON tools include formatting, minifying, validation, key sorting, JSON/YAML conversion, JSON-to-CSV, JSON-to-TypeScript and JSON Lines conversion
• Right-click JSON keys or values to copy the JSON path, key or value
• CSV-to-JSON conversion with automatic delimiter detection
• Base64 and Base64URL encoding and decoding
• Gzip/Base64 conversion, hexadecimal/ASCII conversion, URL encoding/decoding and HTML entity encoding/decoding
• Decode JWT data without verification
• Generate SHA-256, SHA-512, SHA-1, MD5 and CRC32 hashes
• Text tools include upper, lower, Title, camel, snake, kebab and sPoNgE case conversions
• Sort and reverse lines, reverse strings, remove duplicate lines, trim whitespace and collapse blank lines
• ROT13 transformation plus word, line and character counting
• Convert binary, decimal and hexadecimal numbers

• Insert UUID v4 and UUID v7 values

• Multiline find and replace supports matches spanning line breaks
