Add your PARQUET file
Drop one or more .parquet files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
PARQUET to JSON
Converting a .parquet font to .json repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.

Converting a .parquet font to .json repackages the same glyphs and metrics for a different delivery target. A .parquet file is a self-describing columnar dataset: values from the same field are stored together so an analytics engine can read only the columns and row groups a query needs. It is designed for compact long-term storage, unlike Arrow IPC, which is optimized for immediate in-memory access.
A .json file holds JavaScript Object Notation: nested objects, arrays, strings, numbers, booleans, and null written in a strict text syntax. It is the default data language of the web — most APIs speak nothing else. For this route the practical draw is parsers ship in the standard library of essentially every language and readable by humans and machines alike — balanced against no comments — a perpetual annoyance for configuration files, which is worth knowing before you commit a large batch.
Why convert PARQUET to JSON?
The practical trigger for this conversion is usually a mismatch: with .parquet, not human-readable and awkward to modify in place. Switching to .json buys you parsers ship in the standard library of essentially every language, which is why it is the better fit for rEST and HTTP API request and response payloads. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
PARQUET vs JSON at a glance
| Aspect | Apache Parquet (.parquet) | JSON data (.json) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | columns are split into row groups and pages, allowing a reader to skip both irrelevant columns and ranges of rows | exactly six value types; no dates, no comments, no trailing commas — the strictness is deliberate |
| Strongest at | storing analytics tables in a data lake or object store | rEST and HTTP API request and response payloads |
| Weak spot | not human-readable and awkward to modify in place | no comments — a perpetual annoyance for configuration files |
Pick JSON as the output
Select .json in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if JSON is selectable, the route is real and validated.
Convert on your device
Press Convert. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid JSON file. Outputs keep the original filename with the .json extension.
PARQUET to JSON questions, answered
Will converting PARQUET to JSON lose quality?
There is no visual quality to lose — parquet is lossless-oriented and json is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert PARQUET files here?
Yes — the .parquet file is processed inside your browser tab and never uploaded. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip. Close the tab and the file is gone from memory.
Where will the JSON file work?
Browsers parse it natively through JSON.parse, every mainstream language bundles support, and most editors validate and highlight it out of the box. Viewing a raw .json file is possible in any text editor or browser tab.
Will the JSON file be bigger or smaller than my PARQUET?
It depends on the content: exactly six value types; no dates, no comments, no trailing commas — the strictness is deliberate. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my PARQUET file?
In .parquet, the schema, logical types and column names are read. Key-value metadata is reported where relevant, but CSV cannot carry it and spreadsheets preserve only the displayed table rather than Parquet's physical encodings and statistics. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
