CSV to XYZ Converter
Processing entirely on your device — large files may take a moment.
CSV (Comma-Separated Values) is the universal spreadsheet export format: one table of rows and columns stored as plain text, opened by Excel, Google Sheets and every data tool. Convert XYZ point dumps to CSV or JSON for spreadsheets, or write XYZ out of a table for downstream 3D tools.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the CSV format
CSV (comma-separated values) is the lowest common denominator of tabular data: one table, rows as lines, columns separated by commas, everything plain text. Excel, Google Sheets, every database importer, every data-science library and every scripting language read it, which is why it has survived fifty years of format fashion.
Its weaknesses come from the same minimalism. There are no types (everything is a string until you decide otherwise), no formulas, one table per file, and dialect quirks are legendary: comma vs semicolon locales, quoting rules, and Excel's insistence on re-opening UTF-8 files without a BOM as mojibake. Clean, well-formed UTF-8 CSV with a BOM sidesteps nearly all of it.
+ Strengths
- ✓Universal: Excel, Sheets, databases and code all read it
- ✓Human-readable and diff-friendly
- ✓Streams well — process giant files line by line
! Limitations
- −No types, no formulas, no multiple sheets
- −Dialect chaos: delimiters, quoting, encoding
- −Nested or hierarchical data does not fit
About the XYZ format
XYZ is the plain-text point cloud format — one 'X Y Z' triple per line, '#' comments allowed. Molecular chemistry dumps, LiDAR exports and 3D-scanner output all land in XYZ because every tool can read it.
Conversion is a faithful column mapping: the first three numeric columns become X/Y/Z and any extra columns are preserved, so nothing is lost going to CSV or back.
+ Strengths
- ✓The lowest common denominator of point data
- ✓Human-readable, diff-friendly
- ✓Every GIS/3D tool imports it
! Limitations
- −No rate, scale or projection metadata
- −Large files as plain text
- −No colour/normal standard
Why convert CSV to XYZ?
Think of it as moving your file to the container that fits the job. No types, no formulas, no multiple sheets XYZ works differently: The lowest common denominator of point data If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this CSV to XYZ converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
What about special characters and non-English text?
Everything is handled as UTF-8. When you export CSV for Excel, a UTF-8 BOM is included automatically so Chinese, Japanese, Korean and accented characters display correctly on both Windows and macOS.
How large can my CSV file be?
Since everything runs locally in your browser, the real limit is your device memory rather than an upload cap. Files up to a few hundred megabytes are usually fine on a modern computer; extremely large ones simply take longer.
Are formulas, styles or multiple sheets converted?
No — this conversion extracts the data itself into XYZ. Formulas are exported as their current values, styling is not carried over, and multi-sheet workbooks convert sheet by sheet. For full fidelity between spreadsheet formats, exchange within the same tool family.
