# Does Govform support file uploads? Source: https://govform.com/resources/documentation/article/help-centre-does-govforms-support-file-uploads Topic: Platform & features **Yes, absolutely. Govform supports large uploads, multiple files and streaming bulk-data processing, with your choice of storage, antivirus scanning, document reconstruction and image privacy controls.** Whether you collect a supporting document, a substantial evidence pack or a large reporting dataset, you can control what people upload, how it is checked and where it goes. Use our managed file store or connect your own. ## Handle large files and complete evidence packs - **Large uploads.** Configure standard uploads up to **20 GB per file**, subject to the chosen storage and protection settings. Set a lower limit wherever your service needs one. - **Multiple files.** Collect up to **100 files in a multiple-file component**, with a separate size limit for each file. - **Clear evidence requirements.** Restrict extensions or MIME types, make uploads mandatory where needed, and use conditional questions or pages to request only relevant evidence. - **Easy checking and review.** Show filenames, file view links or download links on Check Answers pages, so users and authorised reviewers can inspect the evidence. ## Process substantial CSV and Excel submissions Bulk Data goes beyond storing a spreadsheet. Govform uses **streaming, row-by-row processing** to validate CSV files or a selected XLSX worksheet in the background, making it suitable for substantial structured returns. - **Validate at scale.** Support datasets with up to **5 million data cells** across up to **200 configured columns**—for example, 500,000 rows with 10 columns. - **Define what good data looks like.** Check required values, text lengths, integer and decimal ranges, dates, true/false values, permitted choices and uniqueness. - **Help respondents resolve problems.** Present validation results and, when enabled, let people correct selected batches of up to 1,000 rows before confirming the dataset. - **Keep source and validated data distinct.** Retain the original upload alongside the confirmed CSV, including respondent corrections, so downstream systems receive the version you intend. - **Move large datasets onward.** Stream the confirmed CSV or original source to a configured file store, or retrieve it through the streaming download API. ## Use our file store or yours Keep evidence in the storage that fits your organisation | File store | What it gives you | | --- | --- | | Govform managed storage | A platform-managed destination for your service evidence, with integrated retrieval, retention handling and in-place antivirus scanning when configured. | | Your SharePoint site | Collect evidence into your selected site and folders, alongside the documents and permissions your team already uses. | | Your Amazon S3 bucket | Store files in your own configured bucket, with your organisation's storage policies. | | Your Google Cloud Storage bucket | Keep uploaded evidence within your configured Google Cloud storage. | | Your Azure Blob Storage container | Send evidence into your configured Azure container and existing storage arrangements. | Normal Govform view and download links work with the configured stores, so using your own storage still gives people a joined-up service experience. External stores retain their own access and retention policies. ## Choose how files are scanned and protected For customer-owned stores, **Govform antivirus scanning is optional**. You can add our checks to your storage arrangement or use the destination's own controls: - **Scan before transfer.** Govform checks the file first and transfers it to your store only after a clean result. - **Scan in parallel.** Run the Govform scan alongside the destination upload. A detected threat rejects the upload and triggers removal of the destination copy. - **Use your own scanning arrangements.** Transfer without a Govform AV scan when your organisation chooses to rely on its own storage and security controls. Govform managed storage uses in-place scanning when the platform's scanning service is configured. CDR follows a scan-first process and requires the original to pass scanning before reconstruction and transfer. Add protection that suits the evidence you need | Capability | What it does | | --- | --- | | Content Disarm and Reconstruction (CDR) | Reconstruct supported documents and images to reduce risk when reviewers open evidence. CDR is available on single-file components, with a separate processing size limit. | | Face blurring | Detect and blur faces in JPEG or PNG images through CDR image processing, reducing unnecessary exposure of people in photographs. | | Metadata removal | Strip GPS, camera, timestamp and other metadata from JPEG or PNG images before storage or onward transfer. | | Image resizing | Automatically reduce large JPEG or PNG images to Full HD dimensions to keep evidence manageable. | ## File sizes and processing limits at a glance Choose limits for the upload, protection and onward delivery | Upload or processing route | Limit | | --- | --- | | Standard uploads | Configurable up to **20 GB per file**. Storage, scanning and service policies can impose lower limits. | | Multiple-file components | Up to **100 files** per component; the configured size limit applies to each file. CDR uses a single-file component. | | Bulk Data CSV/XLSX | The source file follows its upload component's size limit. Validation supports up to **5 million data cells** and **200 configured columns**. | | CDR-protected uploads | **50 MB by default**, or the component's limit if lower. The platform's configured CDR processing cap determines the maximum. | | Govform AV for external stores | The current scanning transfer supports files up to **5 GB**; a lower component or destination limit still applies. | | Files embedded in API requests | **25 MiB of combined raw files per API action**, with Base64 encoding adding approximately one third. Use file-store transfers or streaming downloads for larger evidence. | For evidence-heavy services, you can choose a large-file route and the right level of protection separately.
