Features

Quap works on your computer, so your files stay with you. Here is what you can do with it.

• EditorTabs, a command palette, a project tree and a fast editor made for data files.

  Open a file or a folder, or just paste. Format, clean and sort from the toolbar, find and replace across all open documents, and get back anything you copied from the clipboard history.

  • Ten formats, detected automatically.
  • Every command a few keystrokes away with ⌘⇧P.
  • Find and replace, with regular expressions, across all open documents.
  • Older encodings like Windows-1252 and ISO-8859-9 work too.
• VisualizeRead the same document as a tree, a graph, a table or a chart.

  Edit values right in the tree. The graph shows how things connect. Lists of records become a table you can filter, and Analysis turns them into charts. SQL scripts get a table diagram and Markdown renders with its Mermaid diagrams.

  • Right-click a value to copy, mask, sort or delete it.
  • Filter and sort tables, then export them to CSV or Excel.
  • Group and count your data and see it as one of 15 chart types.
  • Save any view as PNG, JPEG or PDF.
• ToolkitConvert, compare and check data without hunting for the right tool.

  Convert between JSON, YAML, XML and CSV, or turn data into SQL. Translate queries between databases, generate classes from a sample response, compare two lists, check an OpenAPI spec and take a curl command apart. Hashing, encryption and JWT tools are on the toolbar.

  • Translate SQL between PostgreSQL, SQL Server, MySQL, MariaDB, Oracle and SQLite, or into C# LINQ.
  • Classes for C#, Java, TypeScript and Python.
  • Compare two lists: what's in both, what's in only one, what repeats.
  • Record a few steps and replay them later.
• Large filesOpen, search and edit files of any size.

  Multi-gigabyte exports open in seconds and scroll as smoothly as small files, because Quap never loads the whole file at once. Search them, change or mask values across the whole file, convert them to CSV, let the AI work on them, and undo any change.

  • Open and scroll files of any size.
  • Edit, mask and sort across the whole file, with undo.
  • Compare two large files side by side.
  • One license for up to three computers.
• MCPGive Cursor and Claude Desktop Quap's tools.

  quap-mcp connects AI coding tools to Quap. Ask your editor to validate a file, convert a config, translate a query or mask a sample, and it uses Quap to do it, on your computer. Turn it on with one click in Quap and copy the setup into your editor. It's free.

  • Validate and format JSON and SQL.
  • Convert between JSON, YAML, XML and CSV.
  • Translate SQL between databases and generate code.
  • Mask, filter and analyse data with the same operations as Quap's AI assistant.
  • Check OpenAPI specs, take curl commands apart and explain regular expressions.
  • 29 tools in all, listed in the docs.
