InOneShot 1.1.0: Dark Mode, Bilingual UI, PDF Merging, Drag & Drop — and Linux

InOneShot 1.1.0 is an update to the PDF mail merge app that adds dark mode, a bilingual interface, CSV import, single-file PDF merging, drag-and-drop, and a Linux release.

InOneShot evolves based on how people actually use it, not a roadmap fixed in advance. Version 1.1.0 bundles several requests that kept coming up over the past few weeks: more visual comfort, more accepted data formats, and a simpler output file. Here's what actually changed.

What do dark mode and the bilingual FR/EN interface add?

A button in the top bar switches the app to dark mode, and another switches the interface language between French and English. Both settings are remembered across sessions — no surprise auto-detection based on system settings, you choose and it stays.

How does merging into a single PDF work, on top of the ZIP?

Until now, InOneShot produced one PDF per spreadsheet row, delivered in a ZIP. That's still the default, but a new output option lets you merge all the generated documents directly into a single PDF file — handy for a batch you want to print in one go or archive as one document instead of a hundred separate files.

What do CSV import and drag & drop change?

• CSV files are now accepted as a data source, alongside Excel — automatic delimiter and encoding detection
• The PDF template and data file can be dropped directly into the window, no need to go through the file picker every time
• Double-clicking a placed field opens an edit box to fine-tune its position and format
• The preview can now be browsed row by row, to check how several entries render before running the full batch

Is InOneShot now available on Linux?

InOneShot is now available on Linux via the Snap Store, with the same feature set as the Windows version — including drag and drop. Same logic as VoxCut, our other app: no reason to be locked to a single operating system when the same tools can run everywhere, locally.

The update is available now as a direct download on this site (Windows portable) and on the Snap Store for Linux. The Microsoft Store listing is being updated and will follow in the coming days.
