.ODC file extension

To open .ODC files on Windows, install an ODF-compatible office suite such as LibreOffice.

To open an .odc file, use an OpenDocument-compatible office suite (most commonly LibreOffice) and open it like any other document. Do not rename the extension; .odc is a specific OpenDocument Chart format.

What “reviewed” means on this page

Format fit: whether the “what is this file?” description matches common real-world use of the extension, including category, typical MIME types, and aliases.
Opening paths: whether Windows / macOS / Linux steps read plausibly for current OS dialogs and default apps; we remove fantasy menus and unsafe shortcuts.
Security framing: whether risk notes match the extension class (for example executables vs plain data) and whether affiliate wording does not contradict the security section.
Sources and further reading: whether external links point to vendors, standards bodies, or other primary references where possible; we avoid inventing details we cannot ground.
Limits: this is clarity and safety-messaging QA, not a guarantee that every statement is exhaustive or that every binary you download is harmless.

How to open .ODC files

Use these platform-specific instructions to open .ODC files safely.

Windows

Install an ODF-compatible office suite such as LibreOffice.
In the suite, use File > Open and select the .odc file (or right-click the file > Open with > LibreOffice).
If it opens but looks wrong, try updating LibreOffice and reopening the file.

Mac

Install an ODF-compatible office suite such as LibreOffice.
Open LibreOffice, then choose File > Open and select the .odc file (or Control-click the file > Open With > LibreOffice).
If the file fails to open, re-download or re-copy it to ensure it was not corrupted.

Linux

Use your desktop’s file manager to open the .odc file with an ODF-compatible office suite such as LibreOffice.
If file association is incorrect, choose Open With and select LibreOffice explicitly.
On Linux desktops, MIME detection may rely on the shared-mime-info database; updating it can help if the file is misidentified.

iOS

iOS may not reliably open .odc natively; if it does not preview in Files, transfer the file to a desktop ODF-compatible office suite (for example, LibreOffice) to view or edit it.

Android

Android support varies by app; if your installed office apps do not open .odc, transfer the file to a desktop ODF-compatible office suite (for example, LibreOffice) to view or edit it.

Security notes

An .odc file is commonly a ZIP-based package containing XML; treat unexpected .odc files cautiously because malformed or tampered packages can trigger crashes or security issues in document parsers.
If a received .odc is suspicious, avoid extracting its contents with a ZIP tool and instead open it only in a trusted, up-to-date ODF editor/viewer.
Be cautious with .odc files obtained from unknown sources; confirm the sender and expected contents (a chart document) before opening.

If you did not expect this file

This extension is usually plain data, text, or structured content—not a program by itself. The practical risk is social engineering (a scam attachment or misleading filename). For trusted senders you rarely need heavy-handed antivirus wording; use these tools when you want an extra check on unexpected downloads.

Avast

Avast offers free and premium antivirus software that protects against viruses, malware, ransomware, and phishing. Scan files before opening them to ensure safety.

Norton

Norton 360 delivers comprehensive antivirus protection, VPN, and identity theft monitoring. Scan files for threats before opening to keep your device secure.

Can't open this file?

These are the most common causes and fixes when .ODC files fail to open.

Common reasons

The .odc file won’t open or shows an error
The file opens, but the chart formatting looks different
Linux desktop shows the wrong file type or icon for .odc

Fix steps

Open the file with an ODF-compatible suite such as LibreOffice (use File > Open rather than renaming the file).
Re-download or re-copy the file to rule out a partial download or transfer corruption.
If you suspect the extension is wrong, ask the sender what program created it and request the original/exported format again.

OS-specific troubleshooting

What is a .ODC file?

.odc is the OpenDocument Chart document format in the OpenDocument Format (ODF) family. It is typically a ZIP-based package containing XML and related resources that describe an editable chart document. The associated Internet Media Type is commonly listed as application/vnd.oasis.opendocument.chart.

Background

ODC (OpenDocument Chart) is part of the OpenDocument Format (ODF) standard maintained by OASIS and standardized as ISO/IEC 26300. It is intended for stand-alone chart documents—charts that can be stored and exchanged independently rather than only being embedded inside text documents or spreadsheets.

In practice, .odc files are used in office productivity workflows where charts need to be edited, versioned, or shared in an open, vendor-neutral format. LibreOffice documentation explicitly refers to “ODF Chart” as the file format for stand-alone charts.

Technically, an .odc file is usually a compressed (ZIP) package containing XML files. This means it behaves somewhat like other modern office formats: it is easy to distribute, but if the file is damaged or partially downloaded, it may fail to open because the internal package structure is incomplete.

Common MIME types: application/vnd.oasis.opendocument.chart

Common .ODC issues

The .odc file won’t open or shows an error

This often happens when the required ODF-capable app is missing, the file is corrupted, or it is not actually an OpenDocument Chart file despite the extension.

Open the file with an ODF-compatible suite such as LibreOffice (use File > Open rather than renaming the file).
Re-download or re-copy the file to rule out a partial download or transfer corruption.
If you suspect the extension is wrong, ask the sender what program created it and request the original/exported format again.

The file opens, but the chart formatting looks different

Different ODF implementations may render chart styles, fonts, or layout slightly differently, especially across versions.

Update your ODF editor/viewer to a current version and reopen the file.
Verify required fonts are installed on your system; missing fonts can change layout.
If sharing with others, consider testing the file in another ODF-compatible suite to confirm interoperability.

Linux desktop shows the wrong file type or icon for .odc

Desktop environments often rely on shared MIME databases to recognize file extensions; if the database is outdated, .odc may be misidentified.

Try opening the file directly from within LibreOffice (File > Open).
Update your system’s shared-mime-info package (distribution-specific) and log out/in to refresh associations.
Manually set the default application for .odc to your ODF office suite in your file manager.

FAQ

What does .odc stand for?

It commonly refers to the OpenDocument Chart format: a stand-alone, editable chart document in the ODF family.

What program opens an .odc file?

ODF-compatible office suites typically open it; LibreOffice documentation specifically identifies .odc as the ODF format for stand-alone charts.

Is .odc the same as a spreadsheet file?

No. .odc is for a chart document. Spreadsheets in ODF typically use different extensions (for example, .ods), while .odc is focused on charts.

Can I convert an .odc file by renaming it?

No. Renaming only changes the extension. Use an application that supports ODF and export/save to another format if needed.
