Sweetch

Pre-release. Sweetch is a native macOS file converter that processes supported files on your Mac. It is not released; this page does not offer an app download, announce an App Store listing or set a price.

Third-party notices, source archives and rebuild/relink instructions are separate from the app download. You do not need a support account to read these materials.

Conversion support and limits

The current app includes image, audio, video, PDF, subtitle, archive and text recognition tools, with operation-specific file and encoder requirements. A recognized file extension is not a promise that every file or operation will work. SVG is not supported as an image-conversion or OCR input.

Office support depends on both the input→output pair and the distribution channel. The current Mac App Store-targeted channel policy permits these 14 native Office pairs; this is not an announcement of Store availability:

• PDF → HTML, EPUB or PPTX.
• DOCX or ODT → Markdown.
• CSV, TSV or XLSM → XLSX.
• XLSX, XLSM or TSV → CSV.
• XLSX, XLSM or CSV → TSV.

PDF → PPTX creates page images, not an editable reconstruction of the original text and layout. Native spreadsheet conversion uses cell values; it does not preserve macros, formulas or workbook styling. Other supported Office pairs in the direct-distribution channel require the user’s separately installed LibreOffice. Sweetch does not bundle or download LibreOffice, and that external engine is not enabled in the Mac App Store-targeted channel. Neither the registered operation count nor this list guarantees arbitrary input fidelity.

File access and output

Use the file picker or another supported input action, select an applicable operation, and authorize the input and output folders when macOS asks. Access to an input file does not automatically grant permission to write beside it. If a folder moves or permission expires, select the original intended folder again rather than granting unrelated access.

Keep backups and inspect conversion results before relying on them. A failed or cancelled batch can still have completed output files; read the result and check the output folder before retrying. The explicit Move action changes the source location and is different from conversion.

Finder, watch folders and sharing

The configured Finder shortcut uses the selection in the frontmost Finder window, not arbitrary selections in every application. It is off until configured. macOS may request Finder Automation and file/folder permissions. Pausing the wheel prevents new wheel activation; it does not cancel an active conversion or stop watch-folder processing.

Watch rules can process eligible files automatically after you enable them. After an ordinary restart, stopped rules require manual recovery; Sweetch does not automatically scan or replay old files. Disabling a rule stops queued work, but lets its active conversion finish.

Share hands selected files to the macOS service you choose. OCR and Copy Path can place text or paths on the clipboard. Those services, clipboard settings, cloud-backed folders and backups have their own behavior; local conversion is not a guarantee that user-selected data can never leave the Mac.

Contact and useful diagnostics

Email dmitro.havr.supp@gmail.com with the Sweetch version/build, macOS version, input and target formats, and the exact visible error. Include the distribution channel if you know it. A small, non-sensitive sample may help, but do not send confidential files, passwords, private folder paths or unredacted screenshots by default.
