mojihen! Help

This page summarizes the basic workflow and operating notes for mojihen!. To open the app itself, use /mojihen/app.

1. What mojihen! can do

  • Normalize notation such as width, kana, punctuation, and mixed alphanumeric styles
  • Clean up line breaks, blank lines, and duplicate lines
  • Convert between CSV, TSV, PSV, and spaced text
  • Apply team rules with tab-separated replacement tables
  • Reuse exported settings across projects

2. Basic workflow

  1. Paste text into the input area.
  2. Open conversion settings from the button on the right.
  3. Turn needed conversion options on or off.
  4. Run the conversion and review the result.
  5. Copy the result and paste it into your CMS, spreadsheet, or other destination.

3. Frequently used features

Character conversion

You can choose conversion modes individually for hiragana, katakana, letters, numbers, spaces, punctuation, brackets, symbols, and line breaks.

Delimiter conversion

Choose a target delimiter and switch to CSV, TSV, PSV, spaces, semicolons, or colons without manual edits.

Replacement tables

Write each rule as `before<TAB>after`. Lines starting with `#` are treated as comments. Turn on the replacement-table option to apply them during conversion.

Cleanup options

mojihen! can remove HTML/XML tags, trim leading and trailing whitespace, delete blank lines, delete duplicate lines, remove trailing line breaks, and add full-width spaces at line starts.

Behavior and setting management

It supports changed-text highlighting, character and byte counts, auto-conversion, shortcuts, theme switching, and export/import/reset of settings. Exported JSON also contains replacement tables.

4. Tips for team use

  • Export and share formatting presets so the same quality survives handoffs.
  • Keep separate setting files for each project to avoid applying the wrong rules.
  • Keep before/after examples for tricky cases so rules are easier to review later.

5. How data is handled

  • All conversion runs in the browser.
  • Input text is not sent to external services.
  • Settings are stored locally.

For details, follow the same policy described in the product-page FAQ entry about external transmission.

6. Common stumbling points

The result is not what I expected

Multiple options may be active at once. Turn them on one by one and compare the differences.

Replacement rules are not applied

Confirm the file uses tab separation. Space-separated text may not be parsed as intended.

Columns break when pasting into Excel

Choose the delimiter that matches the format expected by the destination.

The output changes while I type

Auto-conversion may be enabled. Turn it off if you want to review changes manually.

Shortcuts do not work

Check whether shortcut support is enabled. Some browsers or OS settings may limit shortcut behavior. In the input area, `Ctrl+Enter` can also run conversion.
