CleanSheet: Excel Offline CRM

Excel cleaner + lead CRM in one offline app. Someone sends you a spreadsheet full of leads or customers. On a laptop you would clean it in Excel and track calls in a CRM. CleanSheet does BOTH on your phone: open the file, filter and fix the data, then call every lead, note what happened and schedule the next follow-up — and export a fresh Excel anytime. 🤝 WORK YOUR LEADS LIKE A CRM • Tap any row → Call or WhatsApp that lead instantly (phone column auto-detected) • Add comments / call notes on every lead — your full history stays with the row • Schedule follow-ups with a real calendar date picker • Date-wise follow-up view: Overdue, Today, Tomorrow, Next 7 days • Mark a follow-up done — it saves itself into the lead's history • Lead cards show due badges and comment counts at a glance • Reopen the app → continue exactly where you left, with follow-ups due today shown up front • Export comments & follow-ups as extra Excel columns for your team 📂 OPEN ANYTHING • .xlsx, .xls and .csv — from WhatsApp, email, Downloads, anywhere • Multi-sheet workbooks supported, big files up to 30 MB / 50,000+ rows • Card view (each row = a clean readable card) or classic table view with sticky headers 🧹 CLEAN YOUR DATA • Filter by tapping REAL values from your sheet (multi-select, like Excel) — or by conditions: contains, equals, greater than, less than, empty and more • ₹, commas and % understood — "₹ 5,000" filters and sorts as 5000 • Search across all columns, sort any column (numbers sorted as numbers) • Edit any cell or row · add rows and columns · bulk-select and delete rows • Delete, rename and add columns · undo up to 40 steps 📊 INSTANT STATS • Group by any column, total any numbers column — totals, counts, averages with clean bars • Stats follow your filters: pending amount city-wise in two taps 📤 EXPORT SAFELY • Always a NEW .xlsx or .csv — your original file is never touched • All rows or only the filtered rows · save to phone or share in one tap 🔒 PRIVATE BY DESIGN • 100% offline — the app does not even have internet permission • Zero app permissions · no account, no ads, no analytics, no tracking • Your leads and files never leave your phone Perfect for sales teams, real-estate agents, insurance advisors, shopkeepers, tuition teachers, event organisers — anyone whose leads live in Excel sheets. CleanSheet is a spreadsheet cleaner and lead manager, not a full spreadsheet editor — no formulas or charts, by design.
