SlackLogViewer

This is an application to view json files exported from your Slack workspace with Slack-like GUI.
By using this, you can:

• browse any messages that cannot be shown in your workspaces because of the limit of the free plan.
• display threads and reactions.
• search for them by some words or regular expression.
• view or download files, if they are not hidden by the storage limit.

Building

For Windows and macOS, you can download a prebuilt binary from Releases.

If necessary, you can build SlackLogViewer with CMake as in the following commands.

git clone https://github.com/thayakawa-gh/SlackLogViewer
cd SlackLogViewer
mkdir build
cd build
cmake ../SlackLogViewer -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=path_to_install_dir
make
make install
