Slack exports are not built for humans.
They arrive as thousands of JSON files spread across folders, referenced by IDs instead of names. Searching, reviewing, or sharing this data with HR, legal, or auditors becomes manual, slow, and error-prone.
If you've ever thought:
- "How do I search this export?"
- "How do I hand this to legal?"
- "Why is this unreadable?"
You're not alone.
This tool converts a Slack export ZIP into a clean, static HTML archive you can open in any browser.
You get:
- Channel and DM navigation
- User names resolved from IDs
- Full-text search (including prefix search)
- A folder you can share or archive
No server. No cloud processing. Just files you control.

How it works
Keep it boring.
- Drop in your Slack export ZIP
- Generate the archive locally
- Search, review, and share the output folder
That's it.
Who this is for
This tool is built for people who need answers, not dashboards.
- IT & Workspace Admins
- Compliance and HR reviews
- Legal or internal investigations
- Slack migrations and workspace shutdowns
If you need something HR or legal can actually read, this is for you.

FAQ
- What exports are supported?
- Slack exports in the standard ZIP structure. The archive includes whatever data is present in your export.
- Does it include private channels or DMs?
- Usually not. Most workspaces using Slack's Standard Export only include public channel messages and file links. Private channels, DMs/group DMs, and edit/deletion logs are only included when Slack provides an approved Compliance/Enterprise export (or another Slack-approved export that contains that data). This tool does not bypass Slack's export restrictions.
- What about files and attachments?
- Slack exports typically include file metadata and links, not the raw file contents. The tool generates a file-link manifest showing what's referenced vs missing so you can track what was shared.
- Does it work offline?
- Yes. The generator runs locally. The output is static HTML you can open in any browser without an internet connection.
- Is my data secure?
- Your data never leaves your machine. No uploads, no Slack tokens, no cloud processing.
