BOM to TXT Converter

BOM to TXT Conversion Explained

Converting .BOM (Bill of Materials) files to .TXT (Plain Text) changes a structured component list or a binary package manifest into a human-readable, unformatted text string. People convert .BOM to .TXT to read the file contents without needing specialized engineering software or command-line utilities.

You gain universal compatibility and easy searchability. You lose the native file structure. For hardware .BOM files, you lose tabular formatting and spreadsheet capabilities. For macOS binary .BOM files, you lose the machine-readable structure that the operating system uses to verify file permissions and checksums.

This conversion is a bad idea if you need to feed the data back into an installer package, an Enterprise Resource Planning (ERP) system, or a CAD program. Plain text lacks the strict delimiters and metadata required for machine parsing.

Typical Tasks and Users

• System Administrators: IT professionals inspect macOS installer packages (.pkg) by converting the internal binary .BOM to text to audit which files will be installed or modified.
• Hardware Engineers: Designers export parts lists from CAD software and convert them to plain text to share with purchasing departments or external vendors who do not have engineering tools.
• Software Developers: Programmers convert dependency lists into .TXT to run text-based searches (grep) or track changes in version control systems like Git.

Software & Tool Support

• macOS Command Line: Apple includes the lsbom utility natively in macOS to read binary .BOM files and output them as text. The mkbom tool creates them.
• EDA & CAD Software: Programs like Altium Designer, KiCad, and Autodesk Fusion generate and read hardware-based .BOM files.
• Text Editors: Notepad++, Visual Studio Code, and standard Windows Notepad can open .TXT files and raw text-based .BOM variants.
• ERP Systems: Platforms like SAP often import and export bill of materials data, though they prefer structured formats over plain text.

Pros and Cons of the Conversion

Pros:

• Universal Access: Every operating system and device can open a .TXT file natively.
• Security Auditing: Converting binary manifests to text allows security teams to read exact file paths and permissions before executing an installer.
• Version Control: Plain text files are easily tracked by Git, making it simple to see line-by-line changes in a parts list over time.

Cons:

• Loss of Tabular Structure: Hardware .BOM files often contain columns (Part Number, Quantity, Reference Designator). .TXT flattens this, making it harder to read than a spreadsheet.
• One-Way Conversion: You cannot easily convert a plain text file back into a functional macOS binary .BOM.
• No Metadata: Plain text strips out embedded formulas, linked component data, or proprietary CAD metadata.

Conversion Difficulties & Why Convert.Guru

The main technical problem when you convert .BOM to .TXT is format ambiguity. The .BOM extension is not a single standard. A macOS .BOM is a proprietary binary format that requires specific parsing logic to extract file paths, user IDs, and checksums. Conversely, a CAD .BOM might be a delimited text file, an XML document, or a proprietary database export.

A proper conversion pipeline must first identify the specific .BOM variant. If it is binary, the converter must decode the byte structure and map the internal fields into a readable layout. If it is a structured text file, the converter must strip proprietary tags and serialize the data into clean, UTF-8 encoded plain text.

Convert.Guru handles this conversion accurately by automatically detecting the underlying .BOM structure. It extracts the raw data and formats it into a clean .TXT file, bypassing the need for command-line tools like lsbom or expensive CAD licenses.

BOM vs. TXT: What is the better choice?

Which format should you choose?

Choose .BOM when you are keeping the file within its native ecosystem. If the file belongs to a macOS installer, an EDA software suite, or an ERP system, altering the format will break its functionality.

Choose .TXT when you need to share the list with someone who lacks the original software, or when you want to quickly search the contents using standard text tools.

Avoid .TXT if you need to edit a hardware parts list and send it to a manufacturer. For tabular data that requires editing, converting .BOM to .CSV or .XLSX is a much better choice than plain text.

Conclusion

Converting .BOM to .TXT makes sense when you need to audit installer contents or share a hardware parts list with non-technical users. The biggest limitation to watch for is the complete loss of machine-readable structure, meaning the resulting text file cannot be plugged back into the original software. Convert.Guru is a reliable choice for this exact conversion because it handles the ambiguity of different .BOM file types, extracting the necessary data into clean, accessible text without requiring specialized software.
