About this tool
Find and replace text values across any column in a YAML file. Supports plain text matching and regular expressions. A fast way to fix typos, standardise codes, or mask sensitive values before sharing data.
Frequently Asked Questions
Does find & replace in a YAML file change the original file?
No. A new file is created with the replacements applied and offered for download. Your original file is untouched.
Can I use regular expressions for find & replace in a YAML file?
Yes. Enable the regex toggle and enter any standard regular expression. This tool uses RE2 syntax — all common patterns work, but lookaheads and backreferences are not supported.
Which columns are affected by find & replace in a YAML file?
Choose "All text columns" to apply the replacement across every VARCHAR column at once, or pick a specific column from the dropdown for a targeted replacement.
Is my data private?
Yes — completely. Your file is never uploaded to any server. Everything runs locally in your browser using WebAssembly — processing happens entirely inside your tab. Once you close the tab, nothing is retained.
What is the maximum file size?
The free limit is 50 MB. For larger files, performance depends on your device's available memory — most modern machines handle 500 MB to 1 GB comfortably.
