Free online HUS to CSV converter

Brief explanation of the source format

HUS is a Husqvarna/Viking embroidery design file used by some embroidery machines and embroidery software. It stores stitch data, design information, and sometimes color sequence details for machine embroidery. Embroidery digitizers, hobbyists, and sewing professionals use HUS files when preparing designs for compatible embroidery machines.

Typical use cases include machine embroidery, design transfer to supported sewing machines, and editing or re-saving designs in embroidery software.

Brief explanation of the target format

CSV stands for Comma-Separated Values. It is a plain-text table format used to store rows and columns of data. CSV is widely supported by spreadsheet programs, databases, scripting tools, and data-processing software.

The main advantages of CSV are simplicity, human readability, and excellent compatibility across platforms. It is commonly used for data exchange, reports, lists, and importing/exporting structured information.

How to perform the conversion

There is an important limitation here: HUS embroidery files do not normally convert to CSV as a meaningful standard format. A HUS file contains embroidery stitch instructions, while CSV is a generic table format. So the conversion only makes sense if you want to extract stitch or design data into a tabular form for analysis, not to preserve the embroidery design for use in a machine.

The best approach is to use embroidery software or a file parser that can read HUS and export stitch coordinates or design metadata to a table. If your goal is simply to inspect the contents, you can convert the file on 101convert.com for free without installing any software, if that site supports the specific HUS-to-CSV extraction you need.

1. Open the HUS file in compatible embroidery software that supports HUS import.
2. Check whether the program can export stitch lists, needle/color changes, or design metadata in a tabular format.
3. If available, choose File → Export or File → Save as and select CSV as the output type.
4. Choose the fields you want in the CSV, such as stitch number, X/Y coordinates, thread color, or command type.
5. Save the exported file as design.csv.

If your embroidery program does not offer CSV export, use a scripting or conversion tool that can parse HUS files and write CSV output. In that case, the workflow is usually:

1. Convert or read the HUS file with a tool that exposes stitch data.
2. Map each stitch or event to a row in a CSV table.
3. Write the result to .csv for use in Excel, LibreOffice Calc, or another spreadsheet app.

Notes on quality, compatibility, or limitations

This is not a standard one-to-one file conversion. A CSV file cannot preserve embroidery behavior such as stitch sequencing, machine commands, or design rendering. It can only store extracted data in rows and columns.

Compatibility depends on the software used to read the HUS file. Some programs may import HUS but not expose detailed stitch data for export. Others may export only limited metadata. If you need to keep the embroidery design intact, use an embroidery format such as PES, DST, or another machine embroidery format instead of CSV.

For spreadsheet use, CSV is excellent, but remember that it is plain text and does not support formatting, formulas, or multiple sheets in the same way as a workbook file.
