I’m working with two identical tables in a Google Doc and need help with cell replacement.
My situation:
I have two tables with the same structure. The first table has unchecked checkboxes, and the second table has checked checkboxes. When I want to mark a checkbox as complete, I need to copy the corresponding cell from table 2 and replace it in table 1 at the exact same position.
The problem:
Using appendTableCell() adds the copied cell to the end of the row instead of replacing the cell at a specific position. I need to maintain all formatting when copying.
My current code:
function replaceTableCell() {
var document = DocumentApp.openById(document_id);
var bodyContent = document.getBody();
var allTables = bodyContent.getTables();
var sourceCell = allTables[1].getRow(0).getCell(0).copy();
allTables[0].getRow(0).appendTableCell(sourceCell);
}
What I need:
A way to replace or insert the copied cell at a specific index in the target row, not just append it to the end. The formatting must be preserved during the copy operation.
Has anyone solved similar table cell replacement in Google Docs using Apps Script?
You’re trying to replace a cell in a Google Doc table using Apps Script, but appendTableCell() adds the cell to the end instead of replacing it at a specific index. You need a method to replace a cell while preserving its formatting.
Step-by-Step Guide:
Use insertTableCell() and removeCell(): Instead of appendTableCell(), use insertTableCell() to add the copied cell at the desired position, then remove the original cell. This ensures the replacement happens at the correct index without altering the table structure.
Here’s the revised code:
function replaceTableCell() {
var document = DocumentApp.openById(document_id);
var bodyContent = document.getBody();
var allTables = bodyContent.getTables();
var sourceCell = allTables[1].getRow(0).getCell(0).copy();
var targetRow = allTables[0].getRow(0);
// Insert the copied cell at index 0 (first cell in the row)
targetRow.insertTableCell(0, sourceCell);
// Remove the original cell at index 1 (the second cell, which was overwritten)
targetRow.removeCell(1);
}
Remember to adjust the indices (0 and 1 in getRow(), getCell(), insertTableCell(), and removeCell()) to match the specific row and column of your source and target cells.
Verify Table Structure: Before running the script, carefully examine the structure of your tables in the Google Doc. Double-check the row and column indices to ensure they correctly identify your source and target cells. Incorrect indices will lead to incorrect replacements or errors.
Test with a Small Dataset: Start by testing your script with a smaller, simpler table before applying it to your full dataset. This allows you to identify and correct any issues early on, minimizing the risk of accidental data loss or corruption.
Common Pitfalls & What to Check Next:
Index Errors: The most common issue is incorrect row and column indices. Carefully verify these values. Remember that indices start at 0.
Multiple Tables: If you have more than two tables, ensure that allTables[1] and allTables[0] correctly reference your source and target tables respectively. Consider adding error handling to gracefully manage situations where the tables are not found.
Cell Merging: If your tables have merged cells, this approach might behave unexpectedly. You might need a more sophisticated method to handle merged cells.
Formatting Preservation: While copy() generally preserves formatting, complex formatting might require more intricate handling. You might need to explicitly copy and apply formatting attributes instead of relying solely on copy().

Hit this exact problem last year building a document workflow. Don’t mess with inserting/deleting cells - work with what’s already there. Instead of copying whole cells, grab just the checkbox element from your source and swap it into the target cell. Use getChildIndex() to find the checkbox, then removeChild() and insertText() or insertInlineImage() depending on your checkbox setup. This keeps your cell structure intact and only changes the checkbox state. Way cleaner than messing with table cells, plus you skip all the formatting headaches that come with replacing cells. Work at the element level, not the cell level.
there’s actually a simpler approach - just copy the content, not the entire cell. Grab the text and formatting from your source cell, then use clear() and appendText() to paste it into the target. way less of a headache than messing with insertions and deletions.
Been there, done that. Google Apps Script is frustrating when you need precise table manipulation.
Manually handling cell insertion and deletion gets messy fast, especially with multiple tables where you need perfect formatting.
I hit this exact problem a few months back building an automated reporting system. Had to sync checkbox states between template tables and active documents. Apps Script works but becomes a maintenance nightmare at scale.
What saved me was switching to Latenode for document automation. You can set up flows that handle Google Docs table operations way more elegantly. Instead of wrestling with cell indices and worrying about formatting loss, you configure the automation once and it handles all the edge cases.
Latenode can watch for document changes, identify specific cells that need updating, and perform replacements without manually scripting every insertion and deletion. Plus it preserves formatting automatically.
For your immediate need, the insertTableCell() approach mentioned above will work. But if you’re planning to do this regularly or scale it up, automation is the way to go.
Different angle here - try replaceText() with a targeted approach instead. I had checkbox sync issues between tables and found working with text representations way more reliable than messing with cells directly. Grab the checkbox character codes from your source cell with getText(), then use replaceText() on the target to swap just the checkbox symbols. Everything else stays put. This keeps all formatting intact since you’re not touching cell structure at all. Just need to nail down the exact Unicode characters Google Docs uses for checked vs unchecked boxes. Way simpler than the insert-delete mess and won’t break your table layout with complex formatting or merged cells.
