Batch Document Studio
Create personalized multi-page PDFs and images locally with reusable recipes, fit-aware text, custom fonts, and value-free batch preflight.
The problem it solves
Batch Document Studio Batch Document Studio turns a PDF or image template and a CSV/XLSX spreadsheet into a ZIP of personalized PDF or PNG documents. It runs entirely in the browser: templates, recipient rows, rendered documents, and ZIP contents stay on the device.
Who Batch Document Studio is for
- People who need a small, purpose-built utility instead of a broad platform.
- Users working with document generation, spreadsheets, PDF who want the documented v1.1.0 behavior.
- People who prefer an open-source release with visible limitations, source, and license terms.
Intended result
Create personalized multi-page PDFs and images locally with reusable recipes, fit-aware text, custom fonts, and value-free batch preflight.
This summary is reconciled from the current catalog and repository documentation.
Features in v1.1.0
Capabilities below come from the current project README and release documentation.
Reads the first worksheet from CSV and XLSX recipient files.
Preserves duplicate or blank spreadsheet headers by assigning stable unique names.
Previews the first page of PDF templates and full PNG/JPEG templates.
Maps any spreadsheet column to draggable text fields with size, color, alignment, and width controls.
Places fields independently across every page of a PDF template.
Wraps multiline text, shrinks long text to a chosen minimum size, or flags possible clipping.
Verified examples
Screenshots are shown only when the current README references a local source image. Otherwise, repository example files are linked directly.
Verified release evidence
This project does not currently publish a screenshot or dedicated example folder. The current README, tests, changelog, tagged release, and source repository remain the verified examples of its behavior.
Platforms and implementation
The public release claims only the cataloged platforms and technologies.
Supported platforms
- Browser
- Windows
- macOS
- Linux
Built with
- TypeScript
- Vite
- PDF.js
- pdf-lib
Quick start
The shortest documented path into the current release.
- Open the browser application or download the release ZIP and open
index.htmllocally. - Choose a one-page PDF, PNG, or JPEG template up to 25 MB.
- Choose a CSV or XLSX spreadsheet. The first row supplies field names.
- Add fields, select their spreadsheet columns, choose wrapping or shrink-to-fit, and drag them
onto any template page.
- Preview multiple records, choose PDF or PNG, set a filename pattern, and select Build ZIP.
The ZIP contains one file per non-empty spreadsheet row plus a JSON manifest connecting each filename to its original spreadsheet row number.
Current limitations
These boundaries are part of the product and prevent the page from implying unverified capability.
- Custom fonts are user-supplied and are not stored in recipes; reattach the font each session and
confirm its license permits embedding. Complex-script shaping still depends on the selected font and PDF library capabilities.
- PNG output represents the first template page only. Fields mapped to later pages are reported by
preflight and omitted from PNG output.
- PNG output uses the rendered preview resolution. It is not a print-preflight or color-management system.
- The tool does not email recipients, host QR verification records, sign documents, or persist
projects automatically. Portable recipes are explicit downloads and exclude templates and rows.
.xls, password-protected spreadsheets, macros, Google Sheets URLs, and multi-sheet selection are not supported.
Privacy and licensing
Review the actual data boundary before using a tool with sensitive inputs.
Privacy and safety
The production bundle makes no application network requests. All parsing and rendering happens in the browser. The public demo requires a normal page request to GitHub Pages, but uploaded files are not transmitted by the application.
Treat recipient spreadsheets and output ZIPs as sensitive. Batch Document Studio does not encrypt them, delete copies from your downloads folder, verify that you have permission to use a template, or certify that generated documents are legally valid credentials.
Untrusted PDF, image, and spreadsheet files are processed by third-party parsers inside the browser. Keep the browser current and use the documented 25 MB template limit. See [SECURITY.md](SECURITY.md) for private vulnerability reporting.
