Free online XLTM to CSV converter

Some import systems, databases, and data-analysis tools accept CSV but cannot read an Excel macro-enabled template. Converting the template’s worksheet to CSV makes its tabular data easier to exchange, but does not preserve the template’s macros or spreadsheet layout.

What the XLTM format is

.xltm is Microsoft Excel’s macro-enabled template format, based on Office Open XML. It stores reusable worksheet layouts and can contain VBA macros; Excel creates it when saving a workbook as an Excel Macro-Enabled Template. You may receive one when a company distributes a standardized form or spreadsheet for repeated use.

What the CSV format is

.csv stores rows of values as plain text, with fields separated by a delimiter such as a comma or semicolon. It is supported by databases, data-analysis tools, and many spreadsheet programs. CSV is easy to import and inspect, but it does not retain workbook formatting, macros, or multiple sheets.

How to convert XLTM to CSV

Online on 101convert.com

1. Upload the XLTM file on the converter page. You can add several files for batch conversion; the page shows the per-file size limit.
2. Before converting, choose the column separator, character encoding, and sheets to include.
3. Convert the file, then download the CSV output. The conversion runs on the site’s server using LibreOffice.

Offline with desktop software

LibreOffice Calc is free and runs on Windows, macOS, and Linux. Open the XLTM file, select the worksheet to export, then choose File → Save As. Set the file type to Text CSV (.csv), save, and confirm the CSV format when Calc prompts you. In the export dialog, set the character set and field separator if needed.

Microsoft Excel can also export the file. Open the XLTM or create a workbook from the template, select the worksheet to save, then choose File → Save As and select CSV UTF-8 (Comma delimited) (*.csv) or another CSV option available in your version. Confirm any format warning. Excel exports the active worksheet, not the entire workbook.

What changes during conversion

CSV contains one worksheet per file. Exported cells are generally written as their calculated or displayed values; formulas, formatting, charts, macros, and other sheets are not preserved. Check the selected sheet and delimiter before exporting, especially if the receiving program expects a particular separator or encoding.
