Find and replace in a selection in Google Docs, and what to do when Find and replace isn't working

Google Docs' Find and replace always works on the whole document: there is no "selection only" or "in selected text" option. Google's help page for the feature (checked 1 November 2026) lists only two options for documents: "Match case: Matches only words with the same capitalization" and "Match using regular expressions: In Google Docs, matches words based on regular expressions." Replace all therefore changes every match, including the ones in parts you wanted to leave alone. Below: five ways to replace inside one part of a document, then a table of fixes for when Find and replace finds nothing or the wrong thing.

Replace inside one part of a document: five ways

1. Step through with Next and Replace (few matches, no setup)

Open Edit > Find and replace (Ctrl+H, or ⌘+Shift+H on a Mac), type the word, and click Next until you reach the first match inside your part. Click Replace (not Replace all) for each match you want to change and Next to skip the others. Fine for a handful of matches; slow for fifty.

2. Move the part to a new document, replace all there, move it back

1. Select the part and cut it (Ctrl+X).
2. Open a new document (type docs.new in the address bar) and paste (Ctrl+V).
3. Run Find and replace with Replace all in the new document: every match there is inside your part.
4. Select all (Ctrl+A), cut, go back and paste where the part was.

Pasting between Google Docs keeps bold, links, headings and lists. Comments and suggestions on that part do not travel with it, so resolve them first.

3. A Google Sheet, for plain-text lists

If the part is a list (names, references, one item per line), paste it into column A of a Google Sheet. In Sheets, select only the cells you want, open Edit > Find and replace and set Search to "Specific range": Sheets can limit a replace to a range, and it also accepts regular expressions with $1 in Replace with (see our regex guide). Copy the column back into the document. Formatting inside the text (bold words, links) is lost on the way.

Several words to change in that part, not one: copy the part out as plain text into our free bulk find and replace tool, paste your list of find -> replace pairs, check the matches per pair, replace all and paste back (plain text, so bold and links are lost).

4. Apps Script: a "Replace in selection" menu in your document

This adds a menu to the document that replaces only inside the text you have selected. Open Extensions > Apps Script, delete the sample code, paste the script below, click Save, then reload the document. A Selection tools menu appears next to Help. Select text, choose Selection tools > Replace in selection, type what to find and what to replace it with. The first run asks you to allow access to the document.

// Replace plain text (not regex) only inside the current selection.
// Matching is case-sensitive, like Docs with "Match case" ticked.
function onOpen() {
  DocumentApp.getUi().createMenu('Selection tools')
    .addItem('Replace in selection', 'replaceInSelectionPrompt')
    .addToUi();
}

function replaceInSelectionPrompt() {
  var ui = DocumentApp.getUi();
  var f = ui.prompt('Replace in selection', 'Find:', ui.ButtonSet.OK_CANCEL);
  if (f.getSelectedButton() !== ui.Button.OK || !f.getResponseText()) return;
  var r = ui.prompt('Replace in selection', 'Replace with:', ui.ButtonSet.OK_CANCEL);
  if (r.getSelectedButton() !== ui.Button.OK) return;
  var n = replaceInSelection(f.getResponseText(), r.getResponseText());
  ui.alert(n + ' replaced in the selection.');
}

function replaceInSelection(find, replaceWith) {
  var sel = DocumentApp.getActiveDocument().getSelection();
  if (!sel) throw new Error('Select some text first (a blinking cursor is not a selection).');
  var T = DocumentApp.ElementType;
  var count = 0;
  sel.getRangeElements().forEach(function (re) {
    var el = re.getElement(), type = el.getType();
    if (type !== T.TEXT && type !== T.PARAGRAPH && type !== T.LIST_ITEM) return;
    var text = el.editAsText(), s = text.getText();
    var from = 0, to = s.length - 1;
    if (re.isPartial()) { from = re.getStartOffset(); to = re.getEndOffsetInclusive(); }
    var hits = [];
    for (var at = s.indexOf(find, from); at !== -1 && at + find.length - 1 <= to;
         at = s.indexOf(find, at + find.length)) hits.push(at);
    for (var i = hits.length - 1; i >= 0; i--) {   // back to front keeps offsets valid
      var end = hits[i] + find.length - 1;
      if (replaceWith) text.insertText(end + 1, replaceWith);
      text.deleteText(hits[i], end);
      count++;
    }
  });
  return count;
}

Only the matched characters change, so the rest of the selection keeps its formatting; the new text takes the formatting of the character before it. Limits: a match must lie fully inside the selection, and a match that runs across an inline image, smart chip or equation is not found. Tables are covered when you select text inside the cells; a selection that starts outside a table and ends inside it skips the table. Run it on a copy (File > Make a copy) the first time.

Tested on 1 November 2026 with node against a small mock of DocumentApp: a partial selection inside one paragraph, a selection across three paragraphs, matches just outside the selection left alone, an empty replacement, a replacement that contains the search word, no selection, and the menu prompts. Not yet run in a live Google Doc; tell us at replacekit@tuper.app if it behaves differently.

5. ReplaceKit: "Selection only" checkbox (add-on, not listed yet)

ReplaceKit is a Google Docs add-on we are building. Its sidebar has a Selection only checkbox: tick it and every match outside the text you selected is ignored, with a preview list of the matches before you replace. It works together with match case, whole word, regular expressions with $1, and \n for line and paragraph breaks. Selection only is in the free version, with no click limit or trial. Pro ($6/month or $48/year) adds bulk lists of find => replace pairs, replace with formatting and saved rule sets. It is not in the Google Workspace Marketplace yet, so you cannot install it today.

Find and replace not working in Google Docs: causes and fixes

On a long document Replace all can take a while and the page may stop responding for a moment; wait for it rather than clicking again. Undo (Ctrl+Z) reverses a Replace all.
