Add your XLSM file
Drop one or more .xlsm files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Converting a .xlsm file to .txt extracts the document's content from its office package into a portable form. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Converting a .xlsm file to .txt extracts the document's content from its office package into a portable form. An .xlsm file is a Microsoft Excel workbook that is allowed to carry VBA macros. The grid itself is stored exactly as in an .xlsx package — SpreadsheetML worksheets plus a shared-string table — with one extra part holding the compiled macro project.
A .txt file is plain text: nothing but a sequence of characters and line breaks, with no fonts, styles, or embedded objects. It is the lowest common denominator of documents — every computing device of the past several decades can open one. For this route the practical draw is opens everywhere, indefinitely — no format rot possible and the smallest possible representation of textual content — balanced against no formatting, images, or tables of any kind, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .xlsm, the most heavily abused document format in phishing campaigns. Switching to .txt buys you opens everywhere, indefinitely — no format rot possible, which is why it is the better fit for notes, to-do lists, and drafts that must outlive any particular app. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | Macro-enabled Excel workbook (.xlsm) | Plain text (.txt) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | same OOXML package as .xlsx: xl/worksheets/sheetN.xml, xl/sharedStrings.xml, styles, and a workbook relationship graph | no internal structure at all — bytes plus an assumed text encoding are the entire format |
| Strongest at | financial models and reporting workbooks with automated refresh or formatting | notes, to-do lists, and drafts that must outlive any particular app |
| Weak spot | the most heavily abused document format in phishing campaigns | no formatting, images, or tables of any kind |

Select .txt in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TXT is selectable, the route is real and validated.
Press Convert. The package is unzipped in memory and its XML content parsed locally; nothing is uploaded.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid TXT file. Outputs keep the original filename with the .txt extension.
There is no visual quality to lose — xlsm is text-oriented and txt is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Yes — the .xlsm file is processed inside your browser tab and never uploaded. The package is unzipped in memory and its XML content parsed locally; nothing is uploaded. Close the tab and the file is gone from memory.
Notepad, TextEdit, every code editor, every browser, and every phone open .txt without hesitation. It is the one document format with genuinely universal support across operating systems and decades.
It depends on the content: no internal structure at all — bytes plus an assumed text encoding are the entire format. Convert one representative file first and compare before batch-processing a large set.
In .xlsm, docProps/core.xml and docProps/app.xml carry author, dates, and the generating application; tabular exports such as CSV keep none of it. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
