Just between us, is Maya still considered one of the top internal talent for this round?

I'd expect so given last year's numbers, but Chuck said they were reviewing the bonus pool again.

Worth flagging to HR before the next cycle. The bonus gap is going to raise questions.

What you actually
get from Slack

Slack exports are built for machines, not for people reviewing them. Everything you need is in there, buried under thousands of files.

A Slack export arrives as a single ZIP file. Inside, every conversation is split into its own folder. One for each channel, one for each direct message, one for each group DM. Inside each folder, a separate JSON file for every day that had messages.

For a workspace with a year of activity, that's easily 50,000 to 150,000 individual files. User IDs instead of names. Unix timestamps instead of dates. Reactions, replies, threads, bots, and system messages all interleaved together. Perfectly structured, if you're a computer.

JSONstatus turns all of it into one clean, searchable, chronological document.

Everything you need to
make sense of a Slack export

Drop in your ZIP file. Get one reviewable document. No configuration, no third-party upload, no subscription.

Flexible term search

Search across every message with whole-word matching, starts-with patterns, or exact phrases. Combine terms with OR. Case-insensitive by default.

Channel and sender filters

Narrow down to specific conversations or specific people. Filter by date range. See live match counts as you refine.

Chronological merge

All matching messages combined into one timeline, sorted by timestamp across every channel. Grouped visually by sender so conversations read naturally.

User ID aliasing

Deactivated users often appear as raw Slack IDs. Assign a real name once and it replaces the ID everywhere in your output: viewer, exports, and audit log.

Defensible review

Every exported message carries a sequential Bates-style number and a reference to its source JSON file. A search log records exactly what was searched and when.

Nothing leaves your machine

No cloud upload. No "just for processing". No analytics. No telemetry. Every byte of your export stays on your own Mac, forever. The only network call the app makes is a one-time licence check.

From export ZIP to
reviewable document

No configuration required. No forwarding to a third party. Just open the app and point it at your export.

01

Drop in your ZIP

Drag your Slack export ZIP into the app. JSONstatus unpacks, parses, and indexes everything locally in seconds.

02

Search and filter

Enter your search terms. Whole words, phrases, or starts-with patterns. Narrow by channel, sender, and date range.

03

Preview and refine

Live match counts show you whether you're on track. Preview the output, tune the terms, assign names to any unresolved user IDs.

04

Export for review

Produce a single self-contained HTML document: clean, chronological, Bates-numbered, ready for review, redaction, or print-to-PDF.

Built for anyone reviewing
sensitive chat data
Legal

Small-firm legal and paralegals

You've received a Slack export for disclosure or an internal matter. Enterprise ediscovery platforms are out of budget. JSONstatus turns the JSON into a reviewable document your partner can work with, for a one-off cost.

HR

HR investigators

You're investigating a workplace complaint involving Slack communications. Confidentiality is non-negotiable. JSONstatus lets you search terms, aliases, and date ranges without sending data to any third party.

Compliance

Compliance and internal audit

You need auditable review of internal communications: regulatory matters, policy violations, data handling. Every search produces a log. Every export carries Bates-style numbering. Defensibility built in.

Your data is never uploaded, never scanned, never touched by us

Slack exports contain privileged communications, HR confidences, personal data, and commercially sensitive information. Most review tools ask you to upload all of that to a cloud platform, creating a fresh confidentiality risk on top of the matter you're already investigating. JSONstatus does the opposite: every byte of your export stays on your own machine. Parsing, indexing, searching, and exporting all happen locally. The only network call the app ever makes is a one-time licence check that sends nothing but your licence key. No telemetry, no analytics, no "helpful" cloud features. Ever.
