How do I apply the replace changes listed by the JSON output of diff command ?

Simply with a Nodejs script :

const _ = require('lodash');
const path = require('path');
const fs = require('fs').promises;

try {
    // TODO replace with path to your file in develop or whatever branch
    let originalFilePath = path.resolve(__dirname, "fr.json");
    let jsonData = await fs.readFile(originalFilePath, 'utf8');
    let currentObj = JSON.parse(jsonData);

    // TODO replace with path to the file generated by diff command
    let changesFilePath = path.resolve(__dirname, "diff_fr.json");
    let jsonData2 = await fs.readFile(changesFilePath, 'utf8');
    let changesFile = JSON.parse(jsonData2);
    let changes = changesFile.changes;

    // Proper variable for that
    let result = Object.assign({}, currentObj);

    // Add changed values
    // (Feel free to edit the file generated by diff command if you want to override some changes)
    for(let modifiedField of changes.filter(c => ["REPLACED"].includes(c.type)) ) {
        _.set(result, modifiedField.key, modifiedField.newValue);
    }

    // write result
    // TODO Add a path for destination
    await fs.writeFile("", JSON.stringify(result, null, 4));

} catch(err) {
    console.warn("Something bad happend");
    console.error(err);
    process.exit(1);
}
