Hi there, I understand you need a lightweight cross-platform mobile app (iOS + Android) that lets your team enter data via a form mapped 1:1 to an Excel (.xlsx) sheet, work fully offline, and auto-sync new rows to a cloud-hosted master file once connectivity returns. I’ll build this using React Native or Flutter, with offline-first storage, strict field-level validation, auto-save after each input, and a reliable sync layer to OneDrive, Google Drive, or an agreed cloud location. The app will safely append rows, handle airplane-mode test cycles, and be delivered with clean source code, signed builds, and clear setup docs. I’ve built offline-capable data collection apps before and can deliver this cleanly and reliably. Message me to confirm the Excel structure and sync rules—I’m ready to start.

@Kartoos

Hi, I can deliver the app in couple of days....I will use Ionic/Capacior for mobile apps and PHP for backend....Please share the example excel sheet and details about what columns/data fields will be dropdown etc. thanks

@DeveloperStation

Hi Amanpreet, We’ve developed a similar app that lets users upload images and PDFs, extracting data using AI and sending it to a Google Sheet. We also built a web app for admins to manage uploaded files and validate extracted data, ensuring only accurate information is sent to the sheet. For your project, we can use a library like SheetJS to read and write Excel files directly, or we can integrate with Google Sheets and OneDrive APIs to manage data more efficiently. This way, we can avoid issues with Excel file formats and focus on delivering a reliable solution. We’re experts in both React Native and Flutter, and we can choose the best framework based on your specific requirements. With us, you’ll get a fully optimized app that works seamlessly across all devices. Let’s schedule a quick 10-minute call to discuss your project in more detail and see if I’m the right fit for your needs. I’m looking forward to hearing more about your exciting project. Best, Adil

Hello, I can build a lightweight, reliable cross-platform mobile app** that lets your remote team enter records directly into an existing Excel (.xlsx) file, with a strong focus on offline reliability, data integrity, and simplicity. I’ve delivered similar form-based data capture apps where offline-first behavior and accurate sync are critical. Key Highlights • Single codebase for iOS & Android (React Native or Flutter) • Offline-first workflow with automatic sync when connection returns • Queue-based sync tested with airplane → offline → online cycles • Form UI mapped 1:1 to Excel columns you provide • XLSX read/write & append-row handling • Cloud storage support (OneDrive, Google Drive, or agreed option) • Strong field-level validation (required, ranges, dropdowns) • Friendly inline validation messages • Auto-save after each field to prevent data loss • Clean, well-commented, App Store & Play Store–ready code Happy to review your sample Excel sheet and discuss stack, sync approach, and timeline. Regards Praggya

Hello! As per your project post, you’re looking to build a lightweight cross-platform Data Entry Application that allows your remote team to enter records directly into an existing Excel file, with offline support and seamless syncing. The goal is to provide a reliable, user-friendly data entry interface that works both on iOS and Android, handles validations, and ensures no data is lost even when connectivity is intermittent. My focus will be on delivering a simple, form-based interface mapped to your Excel columns, featuring field-level validation, auto-save after each entry, and robust offline queuing with automatic synchronization once the device is online. The app will connect to a cloud location such as OneDrive or Google Drive to append rows reliably, supporting multiple offline-online cycles without data loss. I specialize in Flutter and React Native for cross-platform mobile development, with experience in offline-first applications, cloud integration, and robust data validation. My approach prioritizes reliability, intuitive UX, and clean, maintainable code so the solution can scale or be extended in the future. Let’s connect to review the Excel structure, validation rules, and preferred cloud sync workflow to finalize the approach and ensure smooth implementation across both platforms. Best regards, Nikita Gupta.

@mayankinnovative

Hello, I’ve read the full requirements carefully and understand this is a cross-platform mobile app (single codebase) that allows field staff to enter data into a fixed Excel (.xlsx) structure with strong offline support and reliable sync. I will build this using a proven cross-platform stack (Flutter or React Native) with the following approach: • Form-driven UI mapped exactly 1:1 to your Excel column order • Strong field-level validation (required, ranges, dropdowns) with inline messages • Auto-save after each field change using local storage so no data is lost • Full offline mode with queued records stored locally • Background sync logic that appends rows to the target Excel file once connectivity returns • Safe conflict handling to prevent duplicate or corrupted rows • Cloud storage integration (OneDrive / Google Drive or agreed alternative) using secure APIs • Tested airplane → offline → online sync cycles on both Android and iOS Deliverables I will provide: • Complete, well-commented source code • Android signed build (internal testing) • iOS TestFlight-ready build • Clear README explaining setup, Excel path change, and build steps I have 15+ years experience in software development and have delivered multiple offline-first mobile data capture systems where data integrity is critical. I focus on clean architecture so future changes (new columns or rules) are easy. Thanks for considering my proposal.

@AshraKalsoom

Hello amanpreet2008, I have carefully reviewed the project requirements for the development of a cross-platform mobile data entry app. I propose to create a lightweight application that enables remote teams to enter records directly into an existing Excel file on both iOS and Android platforms. To ensure the success of the project, I plan to implement offline functionality for seamless work without coverage, data validation for accurate inputs, and auto-save features to prevent data loss. I would like to confirm if the cloud storage location for the Excel file is pre-determined or open for discussion. I am confident in my ability to deliver a user-friendly and efficient solution that meets your needs. Looking forward to further discussing the project details. Best regards, Ashra

@bradw14

I can deliver a mobile application with offline functionality, data validation, and auto-save features for remote data entry into an Excel (.xlsx) file for both iOS and Android platforms — on time, on budget, and with excellence. Can the existing Excel file contain formulas and conditional formatting that need to be preserved after new rows are added to the sheet? In Digital Product Development, Custom App & Website Development, and AI-Powered Automation/Agents, I bring years of proven experience delivering similar solutions for both corporate clients and startups. Recently, I built a custom mobile app using Flutter that synchronized offline data seamlessly with cloud storage, ensuring data integrity and reliability. If this sounds aligned, let’s connect and map out the next steps. Regards, Brad Wilson
