Local-only workspace
Build repeatable list workflows without uploading your data
Import TXT, CSV, or JSON, arrange deterministic cleanup steps, preview the result, and save a reusable recipe. Your dataset stays in this browser tab unless you explicitly export it.
Private by default
Inputs and results are never included in recipe saves or share links.
Deterministic steps
Every operation is explicit, reorderable, and repeatable on another file.
No account required
Recipes are stored locally only when you press Save recipe.
Workflow Studio
Input → recipe → result
Step 1
Add a local dataset
Files are read locally. CSV fields become items in reading order; JSON accepts arrays of strings, numbers, or objects.
Step 2
Build the recipe
Local rule parser—no AI service or API key. Example: “trim spaces, remove empty lines, deduplicate ignoring case, sort ascending”.
No steps yet
Add an operation or describe a workflow above. Steps run from top to bottom.
Step 3
Run and preview
Ready. Add input and at least one enabled step.
Preview is capped for responsiveness; exports use the complete result.
This browser only
Saved recipes
Only recipe names, steps, and options are stored. Input and output are excluded.
What a recipe contains
Operation IDs
Known local operations such as trim, deduplicate, filter, sort, replace, or change case.
Safe options
Small settings such as sort direction or a prefix. Unknown operations and malformed options are rejected.
No dataset
Recipe JSON and recipe links deliberately omit pasted text, imported files, output, and filenames.
