What the ITMZ format is
ITMZ is the native mind-map format used by Toketaware’s iThoughts family of applications, including iThoughtsX. It stores the map hierarchy and can include formatting, notes, links, images, and other map data in a packaged file. You typically encounter it when someone sends an iThoughts map or when a map is exported from iThoughts on macOS, Windows, iPhone, or iPad.
What the XLSX format is
XLSX is the XML-based workbook format used by Microsoft Excel and supported by LibreOffice Calc, Apple Numbers, Google Sheets, and other spreadsheet software. It is suitable for sorting topics, adding columns, applying formulas, filtering data, and creating reports. XLSX is preferable when the map’s content needs to be processed as rows and columns rather than edited as a visual branching diagram.
How to convert ITMZ to XLSX
Using iThoughts
- Make a copy of the original
.itmzfile so the source remains unchanged. - Open the file in iThoughts or iThoughtsX.
- Use File → Export → Excel or the equivalent Export command in the application’s sharing menu.
- Choose the Excel workbook format, select an output folder, and save the result with an
.xlsxextension. - Open the workbook in Excel or LibreOffice Calc and check the exported topic columns before sharing it.
If iThoughts presents export settings, choose the option that includes subtopics or child branches. For a large map, export a small test copy first to verify how levels, notes, and links are represented.
Using the online converter
You can convert the file for free on the 101convert.com website without installing software: upload the .itmz file, select XLSX as the output format, start the conversion, and download the generated workbook. Avoid uploading maps containing confidential notes, personal data, or restricted attachments.
Quality and compatibility limits
The conversion changes a hierarchical diagram into spreadsheet data. Branch levels are normally represented by rows or separate columns, while canvas layout, connectors, colors, icons, floating topics, and visual relationships may not survive. Notes and hyperlinks may become cell text, and embedded images or attachments may be omitted or exported separately.
Review merged cells, text wrapping, hyperlinks, and worksheet row limits after conversion. If the map must remain visually editable, retain the original ITMZ file and use a mind-map export such as PDF or an interchange format in addition to XLSX.
