Convert ZIP to CSV Online Free
Export the file listing of any ZIP archive as a CSV — path, size, compressed size, modified date, and CRC for every entry. Ideal for auditing archives without extracting them.
By ChangeThisFile Team · Last updated: March 2026
ChangeThisFile reads the contents of your ZIP archive on a secure server and emits a CSV that lists every entry: full path inside the archive, uncompressed size, compressed size, modified date, and CRC checksum. The original ZIP is never extracted to disk and is auto-deleted after processing. Free, no signup required.

ZIP vs CSV: Format Comparison
Key differences between the two formats
| Feature | ZIP | CSV |
|---|---|---|
| Type | Binary compressed archive | Plain-text tabular data |
| Contents | Many files plus a central directory index | Rows of comma-separated values |
| Human-readable | No — binary structure | Yes — opens in any text editor or spreadsheet |
| Use case | Bundling and compressing multiple files | Tabular audit logs, inventory listings |
| Metadata captured | Per-entry size, CRC, timestamp, attributes | One row per file with metadata columns |
| File size | Often megabytes to gigabytes | Typically kilobytes — just the listing |
| Tooling | Every OS, plus 7-Zip, WinRAR, unzip | Excel, Google Sheets, pandas, any database import |
When to Convert
Common scenarios where this conversion is useful
Audit the contents of a delivered ZIP
When a client or vendor sends a large ZIP archive, export the listing to CSV first so you can verify exactly which files are inside, their sizes, and timestamps before extracting.
Compare two archive snapshots
Generate a CSV listing for each version of an archive and diff them in a spreadsheet to see which files were added, removed, or changed size between releases.
Build a manifest for compliance or backup verification
Produce a tamper-evident CSV manifest of every file in a backup ZIP — path, size, CRC — and store it separately as an integrity check.
Plan extraction storage requirements
Sum the uncompressed sizes from the CSV to know exactly how much disk space the ZIP will need once extracted — useful for cloud or low-storage environments.
Feed an asset index into a database or BI tool
Import the CSV into a database to enable SQL queries over archive contents — find all PDFs over 10MB or every file last modified before a given date, without extracting anything.
Who Uses This Conversion
Tailored guidance for different workflows
For DevOps and IT
- Audit deployment ZIP bundles before release to confirm exactly which files ship
- Diff CSV listings of two backup snapshots to detect missing or new files
- Build automated compliance reports of archive contents without extracting sensitive data
For Data Engineers
- Import the CSV into a database to run SQL queries over archive contents
- Use the listing to plan parallel extraction and ingestion of large dataset ZIPs
For Researchers and Archivists
- Catalog a large research dataset delivered as a ZIP without consuming disk space to extract it
- Create a permanent CSV manifest of an archived collection so future readers can browse the contents at a glance
How to Convert ZIP to CSV
-
1
Upload your ZIP file
Drag and drop your .zip archive onto the converter, or click to browse. Files up to 500MB are supported.
-
2
Server-side listing extraction
Your archive is read on the server using 7-Zip's listing mode. The central directory is parsed and each entry's path, size, compressed size, modified date, and CRC are written as CSV rows. The archive itself is never extracted.
-
3
Download the CSV
Click Download to save the resulting .csv file. The original ZIP is automatically deleted from our servers after processing.
Frequently Asked Questions
No. This produces a CSV listing of what is inside the ZIP — path, size, compressed size, modified date, CRC — without extracting any file contents. If you need a specific file out of the archive, extract the ZIP locally and convert the file you need separately.
The CSV includes: path (full path inside the archive), size (uncompressed bytes), compressed_size (bytes), modified (ISO 8601 timestamp), crc (CRC-32 checksum), and is_directory (true for folder entries). Header row is always included.
Yes — the file listing of a password-protected ZIP is itself not encrypted in standard ZIP files, so the converter can produce a CSV of paths and sizes without the password. AES-encrypted ZIPs with encrypted headers will return an error.
Yes. ChangeThisFile is free with no signup, no watermark, and no usage limits.
Yes. Your ZIP is transferred over HTTPS, read for its directory listing only, and automatically deleted from our servers immediately afterward.
This specific tool targets ZIP archives. We also support 7Z, RAR, TAR, and TAR.GZ archives — try the related conversions or pick the matching converter from the homepage.
Yes. The path column shows the full path of each entry inside the archive, including any subdirectories (e.g. images/photos/cat.jpg). You can sort or group on path prefix to reconstruct the folder tree.
Yes. The output is a standard UTF-8 CSV with a header row and properly quoted fields. It opens cleanly in Excel, Google Sheets, Numbers, and any data tool that imports CSV.
ZIP64 archives are supported up to the upload limit of 500MB. The CSV will include the correct sizes even for large entries inside a ZIP64-formatted file.
If the central directory of the ZIP is unreadable, the converter returns an error rather than a partial CSV. Try repairing the archive with a tool like 'zip -FF' or re-downloading from the source.
