Personas

One app, several cleanup jobs.

The same core loop works across roles: inspect the file, clean the data, review the output, and export with confidence.

Operations

Clean customer, order, inventory, supplier, and support exports before importing them into internal systems.

Marketing

Dedupe lead lists, normalize campaign fields, filter segments, and export clean rows for email and ad platforms.

Data analysis

Prepare raw CSV/XLSX files before they enter analytics workflows, dashboards, notebooks, or databases.

Founders

Fix spreadsheets without one-off scripts, cloud upload tools, or a subscription for a small practical utility.

Developers

Use MCP to inspect and operate on the visible workbook from Claude Code, Claude Desktop, Codex CLI, or Cursor.

Small teams

Give non-technical teammates a visual workflow for repeated spreadsheet cleanup without custom scripts.

Common workflows

Built around jobs that repeat.

The app is not trying to be a BI platform or a spreadsheet suite. It is the preparation step that makes downstream tools cleaner.

CRM import cleanup

Normalize names, emails, statuses, tags, dates, and duplicates before importing customer records.

Campaign list preparation

Filter segments, dedupe leads, clean UTM columns, and export only matching rows.

Vendor or supplier file review

Compare weekly exports, identify missing rows, and generate reviewable workbooks.

Excel-to-system handoff

Clean text, split columns, convert date formats, and remove blank rows before upload.

Agent-assisted data prep

Ask an MCP-enabled agent to inspect, filter, trim, dedupe, export, and save while you watch.
