Convert TAR to JSON Online Free
Extract complete file metadata from TAR archives into structured JSON format. Perfect for DevOps automation, backup auditing, and archive inventory management.
By ChangeThisFile Team · Last updated: March 2026
ChangeThisFile converts TAR to JSON using 7-Zip on a secure server. Upload your archive, and it is processed server-side to extract structured metadata in JSON format, including filenames, sizes, permissions, and timestamps. Files are auto-deleted after processing. Free with no account needed.

TAR vs JSON: Format Comparison
Key differences between the two formats
| Feature | TAR | JSON |
|---|---|---|
| Data type | Tape archive container | Structured metadata listing |
| Compression | None (uncompressed by default) | Plain text, no compression |
| File metadata | Embedded in archive headers | Exposed as readable key-value pairs |
| Permissions | Unix permissions stored in headers | Permissions exported as octal strings |
| Readability | Binary format, requires tar utility | Human-readable, parseable by any language |
| Use case | File distribution and archiving on Unix/Linux | Archive analysis, automation scripts, APIs |
| Processing | Requires extraction to inspect contents | Instantly queryable with standard JSON tools |
When to Convert
Common scenarios where this conversion is useful
DevOps pipeline automation
Parse TAR archive metadata in CI/CD pipelines without extracting files. JSON output can be fed directly into scripts to verify build artifacts, check file sizes, or confirm expected paths are present before deployment.
Backup audit and compliance
Audit server or database backup TAR archives by converting the manifest to JSON. Compare timestamps, file counts, and sizes against expected baselines to detect incomplete or missing backups without restoring them.
Archive inventory cataloging
Catalog large collections of TAR archives by converting each to JSON and storing the metadata in a database. Enables searchable, queryable indexes of archived files across hundreds of archives without extracting any contents.
Security and permission auditing
Extract Unix file permissions and ownership data from TAR archives to audit security configurations. Identify files with overly permissive modes or unexpected ownership before deploying archived configurations.
Configuration management
Inspect configuration deployment archives to verify all expected config files and directories are present with correct timestamps. JSON output integrates easily with Ansible, Chef, or Puppet verification workflows.
Who Uses This Conversion
Tailored guidance for different workflows
For DevOps Engineers
- Verify CI/CD build artifact archives contain expected files and correct permissions before deployment
- Integrate TAR metadata extraction into pipeline scripts to enforce file structure contracts
- Automate pre-deployment checks by parsing JSON output with jq or Python against expected manifests
For System Administrators
- Audit server backup TAR archives to verify all critical directories and config files were captured
- Check file permission integrity in archived configurations before restoring to production systems
- Generate inventory reports from archived log collections for compliance and retention auditing
For Developers
- Inspect deployment package TAR archives to confirm all source files, assets, and configs are included
- Build archive management utilities that display contents without extracting files to disk
- Parse TAR metadata into a database to create searchable catalogs across large archive collections
How to Convert TAR to JSON
-
1
Upload your TAR file
Drag and drop your TAR file onto the converter, or click browse. The file is uploaded over an encrypted connection.
-
2
Server-side conversion
The server extracts your TAR archive metadata and creates a structured JSON file with filenames, sizes, permissions, and timestamps.
-
3
Download the JSON
Save your converted file with the archive metadata. The server copy is automatically deleted after processing.
Frequently Asked Questions
The JSON output includes file names, full paths, file sizes, modification timestamps, Unix file permissions (in octal), owner and group information, and the file type (regular file, directory, symlink). All metadata stored in the TAR headers is exported.
No. Only the archive metadata is read from the TAR headers. The actual file contents remain inside the archive and are never extracted, making the conversion fast and safe for confidential archives.
This tool is designed for standard .tar archives. For .tar.gz or .tar.bz2 files, use a dedicated TAR.GZ converter. Compressed TAR variants require an additional decompression step before the archive headers can be read.
Unix permissions are exported as octal strings (e.g., '0755' or '0644') matching the standard Unix notation. This allows scripts to directly use the values for permission comparisons or restoration workflows.
Symbolic links are listed as entries with a type field set to 'symlink' and a link_target field pointing to their destination path. This preserves the full archive structure including all link relationships.
The upload limit is 50MB for the TAR archive file itself. Since only headers are read and no files are extracted, TAR archives containing gigabytes of total data can be analyzed as long as the archive file itself is under 50MB.
All entries include their full path, so directory nesting is reflected in the path strings. The JSON can represent deep hierarchies exactly as they appear in the archive without losing any structural information.
If the TAR archive headers are unreadable or the file is corrupted, the conversion will fail and return an error message. The conversion requires valid, readable TAR headers to extract metadata.
Yes. The JSON output is standard, well-formed JSON suitable for processing with jq, Python, Node.js, or any tool that can parse JSON. It is designed for easy integration into DevOps and automation workflows.
No. Both the uploaded TAR file and the generated JSON are automatically deleted from the server immediately after the conversion is complete. ChangeThisFile never retains your files.
