    Scrolling / moving in sheet is very slow in certain templates. Attached an excel that is very slow.

    The Devs informed us that the identical rules in the file are causing this issue. You may use the following logic to combine all the rules.

    Object.keys(json.sheets).forEach(function (key) {
    var sheet = json.sheets[key], ruleMap = {};
    if (sheet.conditionalFormats && sheet.conditionalFormats.rules) {
    var rules = sheet.conditionalFormats.rules;
    rules.forEach(function (rule) {
    var key = rule.formula + "_" + JSON.stringify(;
    if (ruleMap[key]) {
    ruleMap[key].ranges = ruleMap[key].ranges.concat(rule.ranges);
    } else {
    ruleMap[key] = rule;
    let newRules = [];
    sheet.conditionalFormats.rules = newRules;

    We updated the original excel file, combine all formulas into one, it has the same effect but doesn't have any performance issues. Please refer to the following excel and let us know if you face any issues.
