About PMDX files
The .PMDX file extension denotes a spreadsheet document created by SoftMaker PlanMaker, the spreadsheet application within the SoftMaker Office suite. Introduced with the 2012 version, this format utilizes a ZIP-compressed container holding XML files to store cell data, formulas, charts, and formatting, similar to the architecture of Microsoft's XLSX format.
The biggest obstacle for .PMDX files is their proprietary nature and lack of interoperability. Unlike standard formats, .PMDX files cannot be opened natively by Microsoft Excel, Google Sheets, or LibreOffice. This creates a significant workflow bottleneck: if you send a PlanMaker file to a client or colleague who relies on the Microsoft ecosystem, they will be unable to access the data without installing SoftMaker's software. Furthermore, these files are often flagged as unrecognized by web-based previewers and email clients.
To restore usability and collaboration, converting the file is usually necessary:
For Editing & Collaboration: Convert to XLSX. This is the industry standard and ensures your data can be manipulated in Excel or Sheets.
For Quick Viewing/Distribution: Convert to PDF. This locks the formatting and ensures the document looks the same on any device.
For Database Import: Convert to CSV to strip formatting and retain only the raw data structure.
Convert.Guru analyzes your PMDX file, detects the exact format, and lets you read the text inside.
If you want to convert PMDX file to XLSX, XLS, XLSM, XLSB, ODS, CSV, TSV, TAB, DIF, SLK, WK1 or WK3, you can use SoftMaker PlanMaker or similar software from the "Spreadsheet Document" category. In the File menu, look for Save As… or Export….
To convert WQ1, XLSM, NOTES, QPW, WK3, WB2, WKS, XLSB, 123, XLS, WB1 or XLSX files to PMDX, try SoftMaker PlanMaker or another comparable tool in the "Spreadsheet Document" category.
The PMDX Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PMDX converter.
