Questions & answers
What can Java Properties ↔ JSON Converter convert?
Convert Java-style properties with continuation lines, escaped separators and Unicode escapes.
Which format rules should I check?
Open UTF-8 files here. Output can use ASCII Unicode escapes for traditional Java loading. Duplicate keys are rejected; comments and ordering are not preserved.
Can I convert several files?
Yes. Open up to 10 files, select the settings and choose Convert files to ZIP. The status table identifies converted and failed files. The downloaded ZIP includes outputs and an audit; failures are not silently treated as successful.
How do I check the result?
Review the converted preview and audit before downloading. Check the stated format limitations, especially timing precision, omitted CSV columns and address metadata. Binary output downloads the actual bytes, not the hex preview.
What are the limits?
Text input up to 200,000 characters; files up to 2 MiB; up to 10 files in a ZIP batch. Table converters allow 1,000 rows and 100 columns.
Is input sent to a conversion service?
The conversion runs locally in a browser worker with bundled scripts. No conversion API is called. Copying and downloads happen only when you click their buttons. Saved comparisons stay in this tab and are cleared by reload. Ad-supported pages can load third-party scripts.
