How to Find & Replace Text in Multiple AutoCAD Drawings
A client gets renamed, a project number changes, a note is wrong on every sheet — and the same text now has to change in dozens or hundreds of DWG files. Here is every practical way to do it, with the honest trade-offs of each.
Full disclosure: docuredo, the site you are on, is method 6 below. Where a free tool is the better fit, this guide says so plainly — that is exactly what makes it worth reading.
1. AutoCAD's FIND command — one drawing at a time
The built-in FIND command (also in AutoCAD LT) searches and replaces across the current drawing, including blocks and attributes, with match-case and whole-word options. Its limit is scope: it works on the drawing that is open, never on a folder.
For three or five drawings, opening each one and running FIND is genuinely the fastest answer, and no tool below beats it. The pain starts when the set is thirty drawings, or when the person fixing the text is not the person with AutoCAD.
2. Script files — free, DIY, sharp edges
AutoCAD can run a script (.scr) against many drawings — via ScriptPro, a batch file, or the command line. Combined with a replacement routine, this is the classic CAD-manager approach: free, fully local, and completely under your control.
The sharp edges: you are writing and testing the automation yourself, error handling is on you, one bad drawing can stall the run, and there is no report of what actually changed beyond what you script. It rewards exactly the person who enjoys building it.
3. Free AutoLISP tools — BFind and srxTEXT
Two mature free tools cover most local batch needs, both loaded inside AutoCAD:
- Lee Mac's BFind processes the current drawing, all open drawings, or a whole directory through ObjectDBX — no need to open each file. Not compatible with AutoCAD LT in its published form. Our detailed BFind comparison.
- ARKANCE's srxTEXT replaces with exact, substring or regular-expression matching, and loads rule pairs from CSV. It works per drawing — batching means driving it with a script processor. Most of it runs on LT 2024+. Our detailed srxTEXT comparison.
If you have full AutoCAD and are comfortable loading a .lsp or .vlx file, these are excellent — free is free. The costs arrive after the run: your license and workstation are occupied for the duration, LT teams are left out, and confirming that hundreds of replacements landed correctly — including the ones inside formatted MTEXT that no ObjectDBX tool can safely touch — is manual checking against a plain text log, or against nothing.
4. Commercial desktop apps — JTB Batch Change
JTB Batch Change (150 USD) drives an installed AutoCAD from Excel worksheets, and goes well beyond text: layer renaming, importing standards, property changes, xref management. If the real problem is drawing standards rather than one wrong string, a tool of this shape earns its license fee. Our detailed JTB Batch Change comparison.
5. ATTOUT and ATTIN — attributes through Excel
For block attributes specifically (title blocks above all), the Express Tools commands ATTOUT and ATTIN export attribute values to a tab-delimited file, let you edit them in Excel, and import them back. Per drawing, attributes only, and do not touch the handle column — but for a title-block sweep with AutoCAD on the desk, it is free and dependable.
6. Cloud batch processing — docuredo
Our product. Upload up to 1,000 DWG files in the browser, enter find-and-replace rules or paste a list straight from Excel, and the genuine AutoCAD engine on Autodesk's cloud applies them to every drawing in parallel. Each file comes back in its original DWG version with a line-by-line audit report; anything that cannot be replaced safely is skipped and flagged, never guessed. Files delete from active storage within 48 hours.
The honest trade-offs: it costs money (per drawing; new accounts start with 3 free credits), it has no regular expressions, and your drawings transit Autodesk's cloud — which rules it out where drawings must not leave the building. Where it wins is everything local tools assume: no AutoCAD seat, no LT limitation, no script to maintain, and proof of what changed.
7. The long-term fix: stop typing values that change
Most batch replacement jobs are self-inflicted, a set of drawings carrying typed text that was always going to change: dates, sheet numbers, project names, client names. AutoCAD's fields exist for exactly this. A title block whose values come from fields — drawing properties, Sheet Set Manager, date fields — updates itself, and the next rename never becomes a batch job.
That does not help the thousand legacy drawings you have today — that is what everything above is for — but it is the difference between curing this once and curing it every project.
Which method fits your situation
| Your situation | Reach for |
|---|---|
| A handful of drawings, you have AutoCAD | Open each and use FIND — no tooling beats 20 minutes of honest work |
| Many drawings, full AutoCAD, comfortable with AutoLISP | BFind (free, whole directories) or srxTEXT (free, regex) |
| Replacements driven by a big Excel list, AutoCAD installed | JTB Batch Change, or paste the list into a cloud batch |
| Attributes only, and you like spreadsheets | ATTOUT/ATTIN Express Tools round trip through Excel |
| AutoCAD LT, or no AutoCAD at all | A browser-based batch service — nothing to load or install |
| The person doing it is not a CAD operator | A browser-based batch service with an audit report to hand back |
| Same values change on every project | Stop replacing: switch the title block to fields and Sheet Set Manager |
One warning that applies to every method: avoid DWG-to-DXF-and-back conversion workflows for text editing. Each conversion is a fidelity risk taken for no benefit that a native method does not already give you.

Questions
Frequently asked questions
Can AutoCAD's FIND command search multiple drawings at once?
No. FIND works inside the drawing that is currently open — it can cover the whole drawing or just the current space, but never a folder of files. For a set of drawings you need a batch method: scripts, an AutoLISP tool, a desktop batch app or a cloud service.
What is the best free way to replace text in many drawings?
If you have full AutoCAD and are comfortable loading AutoLISP, Lee Mac's BFind processes a whole directory via ObjectDBX, and ARKANCE's srxTEXT adds regular-expression matching (driven per drawing, or batched with a script processor). Both are free and capable — and both leave verification of the results to you.
How do I batch-replace text with AutoCAD LT?
With difficulty, locally. LT 2024 and newer run some AutoLISP, but the published BFind is not compatible with LT, and only parts of srxTEXT work there. LT users are the clearest case for a browser-based service, which does not run inside AutoCAD at all.
Can I replace drawing text without any AutoCAD installed?
Yes — with a cloud service. docuredo (our product) processes uploaded DWG files with the genuine AutoCAD engine on Autodesk's cloud: you define rules in the browser or paste them from Excel, and download corrected drawings plus a line-by-line audit report. Online single-file editors exist too, but they work one drawing at a time.
Is converting DWG to DXF and back a good way to edit text?
Avoid it when you can. Every conversion is a chance for fidelity loss, and most converters in that workflow are not AutoCAD. Prefer methods that edit the DWG natively — inside AutoCAD, or with the genuine AutoCAD engine in the cloud.
How do I stop needing batch text replacement in the future?
Use fields instead of typed text for anything that repeats: sheet numbers, project names, dates and title block values driven by Sheet Set Manager or drawing properties update themselves. Batch replacement is the cure for drawing sets that predate that discipline — fields are the prevention.
Want the no-install route?
Create a free account — 3 credits on signup — run a few DWGs and read the audit report, then decide if the cloud batch fits your set.
No credit card. No AutoCAD installation required.
