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.
Converting a .parquet font to .xlsx repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Converting a .parquet font to .xlsx 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.
An .xlsx file is a modern Excel workbook — a ZIP archive of SpreadsheetML XML parts describing sheets, shared strings, styles, and formulas. It has been Excel's default save format since 2007 and the de facto interchange format for tabular business data. For this route the practical draw is vast grid limits compared with the legacy .xls format and documented ZIP-of-XML anatomy — any ZIP and XML library can mine it, which is how in-browser conversion works here — balanced against date-as-serial-number storage causes subtle off-by-one and timezone bugs, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .parquet, not human-readable and awkward to modify in place. Switching to .xlsx buys you vast grid limits compared with the legacy .xls format, which is why it is the better fit for the standard vehicle for exchanging spreadsheets between organizations. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | Apache Parquet (.parquet) | Excel workbook (.xlsx) |
|---|---|---|
| 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 | xl/worksheets/sheetN.xml holds rows of typed cells; text cells usually point into xl/sharedStrings.xml to avoid repetition |
| Strongest at | storing analytics tables in a data lake or object store | the standard vehicle for exchanging spreadsheets between organizations |
| Weak spot | not human-readable and awkward to modify in place | date-as-serial-number storage causes subtle off-by-one and timezone bugs |
| Metadata | 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 | docProps/core.xml carries Dublin Core creator and date fields while docProps/app.xml records the generating application and company — both ride inside the ZIP |

Select .xlsx in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if XLSX is selectable, the route is real and validated.
Press Convert. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid XLSX file. Outputs keep the original filename with the .xlsx extension.
There is no visual quality to lose — parquet is lossless-oriented and xlsx 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.
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.
Excel 2007 onward, LibreOffice Calc, Google Sheets, and Apple Numbers all handle .xlsx, and nearly every data-processing library reads it. Support is equally solid on iOS and Android through the same vendors' apps.
It depends on the content: xl/worksheets/sheetN.xml holds rows of typed cells; text cells usually point into xl/sharedStrings.xml to avoid repetition. Convert one representative file first and compare before batch-processing a large set.
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.
