# CSV Lead Import — Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Allow supervisors to import leads from CSV into an existing campaign via a modal wizard with column mapping and patient matching.

**Architecture:** Client-side CSV parsing with a 3-step modal wizard (select campaign → upload/map/preview → import). Leads created via existing GraphQL proxy. No new sidecar endpoints needed.

**Tech Stack:** React modal (Untitled UI), native FileReader + string split for CSV parsing, existing DataProvider for patient/lead matching, platform GraphQL mutations for lead creation.

### Task 1: CSV Parsing & Column Matching Utility

**Files:**
- Create: `src/lib/csv-utils.ts`

- [ ] **Step 1: Create csv-utils.ts with parseCSV function**

```typescript
// src/lib/csv-utils.ts

export type CSVRow = Record<string, string>;

export type CSVParseResult = {
    headers: string[];
    rows: CSVRow[];
};

export const parseCSV = (text: string): CSVParseResult => {
    const lines = text.split(/\r?\n/).filter(line => line.trim());
    if (lines.length === 0) return { headers: [], rows: [] };

    const parseLine = (line: string): string[] => {
        const result: string[] = [];
        let current = '';
        let inQuotes = false;

        for (let i = 0; i < line.length; i++) {
            const char = line[i];
            if (char === '"') {
                if (inQuotes && line[i + 1] === '"') {
                    current += '"';
                    i++;
                } else {
                    inQuotes = !inQuotes;
                }
            } else if (char === ',' && !inQuotes) {
                result.push(current.trim());
                current = '';
            } else {
                current += char;
            }
        }
        result.push(current.trim());
        return result;
    };

    const headers = parseLine(lines[0]);
    const rows = lines.slice(1).map(line => {
        const values = parseLine(line);
        const row: CSVRow = {};
        headers.forEach((header, i) => {
            row[header] = values[i] ?? '';
        });
        return row;
    });

    return { headers, rows };
};
```

- [ ] **Step 2: Add normalizePhone function**

```typescript
export const normalizePhone = (raw: string): string => {
    const digits = raw.replace(/\D/g, '');
    const stripped = digits.length >= 12 && digits.startsWith('91') ? digits.slice(2) : digits;
    return stripped.slice(-10);
};
```

- [ ] **Step 3: Add fuzzy column matching**

```typescript
export type LeadFieldMapping = {
    csvHeader: string;
    leadField: string | null;
    label: string;
};

const LEAD_FIELDS = [
    { field: 'contactName.firstName', label: 'First Name', patterns: ['first name', 'firstname', 'name', 'patient name', 'patient'] },
    { field: 'contactName.lastName', label: 'Last Name', patterns: ['last name', 'lastname', 'surname'] },
    { field: 'contactPhone', label: 'Phone', patterns: ['phone', 'mobile', 'contact number', 'cell', 'phone number', 'mobile number'] },
    { field: 'contactEmail', label: 'Email', patterns: ['email', 'email address', 'mail'] },
    { field: 'interestedService', label: 'Interested Service', patterns: ['service', 'interested in', 'department', 'specialty', 'interest'] },
    { field: 'priority', label: 'Priority', patterns: ['priority', 'urgency'] },
    { field: 'utmSource', label: 'UTM Source', patterns: ['utm_source', 'utmsource', 'source'] },
    { field: 'utmMedium', label: 'UTM Medium', patterns: ['utm_medium', 'utmmedium', 'medium'] },
    { field: 'utmCampaign', label: 'UTM Campaign', patterns: ['utm_campaign', 'utmcampaign'] },
    { field: 'utmTerm', label: 'UTM Term', patterns: ['utm_term', 'utmterm', 'term'] },
    { field: 'utmContent', label: 'UTM Content', patterns: ['utm_content', 'utmcontent'] },
];

export const fuzzyMatchColumns = (csvHeaders: string[]): LeadFieldMapping[] => {
    const used = new Set<string>();

    return csvHeaders.map(header => {
        const normalized = header.toLowerCase().trim().replace(/[^a-z0-9 ]/g, '');
        let bestMatch: string | null = null;

        for (const field of LEAD_FIELDS) {
            if (used.has(field.field)) continue;
            if (field.patterns.some(p => normalized === p || normalized.includes(p))) {
                bestMatch = field.field;
                used.add(field.field);
                break;
            }
        }

        return {
            csvHeader: header,
            leadField: bestMatch,
            label: bestMatch ? LEAD_FIELDS.find(f => f.field === bestMatch)!.label : '',
        };
    });
};

export { LEAD_FIELDS };
```

- [ ] **Step 4: Add buildLeadPayload helper**

```typescript
export const buildLeadPayload = (
    row: CSVRow,
    mapping: LeadFieldMapping[],
    campaignId: string,
    patientId: string | null,
    platform: string | null,
) => {
    const getValue = (field: string): string => {
        const entry = mapping.find(m => m.leadField === field);
        return entry ? (row[entry.csvHeader] ?? '').trim() : '';
    };

    const firstName = getValue('contactName.firstName') || 'Unknown';
    const lastName = getValue('contactName.lastName');
    const phone = normalizePhone(getValue('contactPhone'));

    if (!phone || phone.length < 10) return null;

    const sourceMap: Record<string, string> = {
        FACEBOOK: 'FACEBOOK_AD',
        GOOGLE: 'GOOGLE_AD',
        INSTAGRAM: 'INSTAGRAM',
        MANUAL: 'OTHER',
    };

    return {
        name: `${firstName} ${lastName}`.trim(),
        contactName: { firstName, lastName },
        contactPhone: { primaryPhoneNumber: `+91${phone}` },
        ...(getValue('contactEmail') ? { contactEmail: { primaryEmail: getValue('contactEmail') } } : {}),
        ...(getValue('interestedService') ? { interestedService: getValue('interestedService') } : {}),
        ...(getValue('utmSource') ? { utmSource: getValue('utmSource') } : {}),
        ...(getValue('utmMedium') ? { utmMedium: getValue('utmMedium') } : {}),
        ...(getValue('utmCampaign') ? { utmCampaign: getValue('utmCampaign') } : {}),
        ...(getValue('utmTerm') ? { utmTerm: getValue('utmTerm') } : {}),
        ...(getValue('utmContent') ? { utmContent: getValue('utmContent') } : {}),
        source: sourceMap[platform ?? ''] ?? 'OTHER',
        status: 'NEW',
        campaignId,
        ...(patientId ? { patientId } : {}),
    };
};
```

- [ ] **Step 5: Commit**

```bash
git add src/lib/csv-utils.ts
git commit -m "feat: CSV parsing, phone normalization, and fuzzy column matching utility"
```

git commit -m "feat: lead import wizard with campaign selection, CSV preview, and patient matching"
```

### Task 3: Add Import Button to Campaigns Page

**Files:**
- Modify: `src/pages/campaigns.tsx`

- [ ] **Step 1: Import LeadImportWizard and add state + button**

Add import at top of `campaigns.tsx`:

```typescript
import { LeadImportWizard } from '@/components/campaigns/lead-import-wizard';
```

Add state inside `CampaignsPage` component:

```typescript
const [importOpen, setImportOpen] = useState(false);
```

Add button next to the TopBar or in the header area. Replace the existing `TopBar` line:

```typescript
<TopBar title="Campaigns" subtitle={subtitle} />
```

with:

```typescript
<TopBar title="Campaigns" subtitle={subtitle}>
    <Button
        size="sm"
        color="primary"
        iconLeading={({ className }: { className?: string }) => (
            <FontAwesomeIcon icon={faFileImport} className={className} />
        )}
        onClick={() => setImportOpen(true)}
    >
        Import Leads
    </Button>
</TopBar>
```

Add the import for `faFileImport`:

```typescript
import { faPenToSquare, faFileImport } from '@fortawesome/pro-duotone-svg-icons';
```

Add the wizard component before the closing `</div>` of the return, after the CampaignEditSlideout:

```typescript
<LeadImportWizard isOpen={importOpen} onOpenChange={setImportOpen} />
```

- [ ] **Step 2: Check if TopBar accepts children**

Read `src/components/layout/top-bar.tsx` to verify it renders `children`. If not, place the button differently — inside the existing header div in campaigns.tsx.

- [ ] **Step 3: Type check**

Run: `npx tsc --noEmit --pretty`
Expected: Clean (no errors)

- [ ] **Step 4: Build**

Run: `npm run build`
Expected: Build succeeds

- [ ] **Step 5: Commit**

```bash
git add src/pages/campaigns.tsx
git commit -m "feat: add Import Leads button to campaigns page"
```

---

### Task 4: Integration Verification

- [ ] **Step 1: Verify full build**

```bash
npm run build
```

Expected: Build succeeds with no type errors.

- [ ] **Step 2: Manual test checklist**

1. Navigate to Campaigns page as admin
2. "Import Leads" button visible
3. Click → modal opens with campaign cards
4. Select a campaign → proceeds to upload step
5. Upload a test CSV → column mapping appears with fuzzy matches
6. Phone column auto-detected
7. Patient match column shows "Existing" or "New" badges
8. Duplicate leads highlighted
9. Click Import → progress bar → summary
10. Close modal → campaign lead count updated

- [ ] **Step 3: Create a test CSV file for verification**

```csv
First Name,Last Name,Phone,Email,Service,Priority
Ganesh,Bandi,8885540404,ganesh@email.com,Back Pain,HIGH
Meghana,,7702055204,meghana@email.com,Hair Loss,NORMAL
Priya,Sharma,9949879837,,Prenatal Care,NORMAL
New,Patient,9876500001,,General Checkup,LOW
```

- [ ] **Step 4: Final commit with test data**

```bash
git add -A
git commit -m "feat: CSV lead import — complete wizard with campaign selection, mapping, and patient matching"
```

---

## Execution Notes

- The wizard uses the existing `ModalOverlay`/`Modal`/`Dialog` pattern from Untitled UI (same as disposition modal)
- CSV parsing is native (no npm dependency) — handles quoted fields and commas
- Patient matching uses DataProvider data already in memory — no additional API calls for matching
- Lead creation uses existing GraphQL proxy — no new sidecar endpoint
- The `useData().refresh()` call after import updates all DataProvider consumers (campaign lead counts, lead master, etc.)
